Windsor & Newton Watercolour Set Review: Professional vs Student Grade Paints

Choosing the right watercolour set can feel utterly overwhelming. Do you splash out on professional-grade paints or start with something more affordable? And what’s actually the difference between Winsor & Newton’s professional watercolor line and their student Cotman range? This Winsor and Newton watercolour review covers both, with particular focus on Winsor and Newton professional watercolour vs Cotman performance.

I’ve been using Winsor & Newton Professional Watercolour tubes for a while now (you might have read about my watercolour palette setup journey). Whilst I haven’t personally used their Cotman range, I’ll cover what makes each line different so you can make an informed decision about which is right for you.

Understanding Winsor & Newton’s Product Range

Before we get into specific sets, it’s worth understanding what Winsor & Newton actually offers. They’ve got two main watercolour lines:

Professional Watercolour – This is their artist grade paints line, featuring high pigment loads, excellent lightfastness, and fine art pigments. These are the serious paints for serious work.

Cotman Watercolours – Their student grade paints, designed for beginners and hobbyists. More affordable, but with less pigment and more fillers in the different formula.

The price difference is significant, but so is the performance. Let’s look at what you’re actually getting with each.

Winsor & Newton professional reviews from artists consistently praise the pigment load and lightfastness, whilst Cotman receives praise as the best student-grade option. This review breaks down both ranges based on actual use.

Winsor & Newton Professional Watercolour Sets: The Tube Options

I’m focusing on two specific professional sets here: the Professional Watercolour Foundation Set (6 x 5ml tubes) and the Professional Watercolour Rich Earth Set (6 x 5ml tubes). Both retail at £40.60, though you can often find them discounted online. I bought both sets together on Vinted for £30 – new and unopened! 

The Foundation: What You Get

This set includes six carefully chosen colours that represent some of Winsor & Newton’s most reliable and versatile pigments. The actual contents typically include colours like:

• Winsor Lemon 
• Raw Sienna 
• Alizarin Crimson
• Hooker’s Green
• French Ultramarine
• Payne’s Gray

As the name suggests, this is a great starting point which has primary colours and some lovely tones. This gives you incredible mixing potential from just six tube paints.

The Rich Earth Set: For Natural Tones

The Rich Earth Set takes a completely different approach, focusing on earthy, natural pigments:

• Perylene Green
• Olive Green
• Naples Yellow
• Light Red
• Caput Mortuum Violet
• Vandyke Brown

This set is brilliant if you’re into landscapes, portraiture, or anything requiring subtle, natural tones. The pigment information provided with each tube helps you understand exactly what you’re working with.

Performance: What Makes Professional Tubes Special?

I’ve been using the Winsor & Newton Professional Watercolour range, and here’s what I’ve found in actual practice:

Pigment Load and Vibrancy

The pigment load in these professional watercolour sets is genuinely impressive. Squeeze out even a tiny amount of burnt sienna or alizarin crimson hue, and the vibrancy absolutely leaps off your paper. Most shades use single fine art pigments, which means your colour mixes stay clean and bright instead of turning muddy.

I’ve found the tube selection across their range covers everything from strong colours like French Ultramarine and permanent sap green to subtle earth tones. The saturation is miles ahead of student grade paints – reds shine boldly (especially permanent rose and quinacridone magenta), and even darker shades like burnt umber keep their punch after drying.

One artist described them as having “beautiful and rich colours,” and I’d agree. Though it’s worth noting that some earth tones can occasionally feel weak and streaky compared to the more vibrant colours.

Flow and Transparency

From my experience with these professional watercolour tubes, the flow is excellent. The paints spread evenly with water, leaving no odd patches or streaks. The flow runs smooth across the shades I’ve used.

Mixing up burnt sienna or yellow ochre? They move beautifully, never clogging your watercolor paper’s texture. The paints include ox gall to help them glide (though this makes them non-vegan, worth noting if that matters to you).

What’s brilliant is how these paints re-wet. Even after drying on your palette, they reactivate quickly with your water brush, giving you vibrant washes every time – a massive advantage over some half pans or rival brands like Daniel Smith watercolors.

Lightfastness and Permanence

Winsor & Newton Professional Watercolour tubes have strong lightfastness ratings. Many colours show high resistance to fading, making them perfect for archival work. Artists can genuinely trust that their paintings will last without significant colour shift over time.

Initial tests revealed no major fading issues, which is honestly a huge relief when you’re investing in quality work. The permanence ratings align with what you’d expect at this higher price point, making them reliable for both professional artists and serious hobbyists.

Colour Range and Mixing Capabilities

The spectrum of colours available across Winsor & Newton’s professional line is extensive. Within the two sets I’m reviewing, you get 12 colours total, but the professional range extends to dozens more options.

Single-Pigment Colours for Clean Mixes

This is where these paints really shine. Single-pigment colours like raw sienna, alizarin crimson hue, and various yellows allow for incredibly clean mixing. When you’re blending Windsor yellow hue with sap green, you get vibrant greens without any muddiness.

Each colour stands strong on its own whilst working beautifully with others. This makes them ideal for artists who need precise colour mixes every time they paint.

Value for Money: Are They Worth It?

Price Comparison

At £40.60 for six 5ml tubes, these aren’t cheap. Some reviewers have found them for around $87 on Amazon US (retail $212), which shows significant discounts are possible if you shop around.

Compared to competitors:

• Cotman range – Significantly cheaper but lower quality
• Daniel Smith watercolors – Comparable or slightly less per ml
• Schmincke – Often better value than Winsor & Newton
• M. Graham – Generally less expensive

The professional line costs roughly double what you’d pay for student grade watercolors from the Cotman line. Is that worth it?

High-Quality Features vs Cost

You’re paying for:

• Strong pigment load and vibrancy
• Excellent flow and easy re-wetting
• High lightfastness and permanence
• Single-pigment formulations for clean mixing
• Consistent performance across colours

For professional artists or serious hobbyists, these features justify the cost. For absolute beginners still figuring out if watercolour is their thing? Maybe start with the Cotman range first.

My recommendation: Look for discounts. Free standard delivery over £59 and free next-day delivery over £75 (if ordered before 4pm) can help offset costs if you’re buying multiple items. Join their mailing list for new product releases and special offers.

The Cotman Watercolour Set: Student Grade Alternative

Now let’s talk about Winsor & Newton’s more affordable option – the Cotman watercolour set. This is where many beginners start (myself included, before I moved to professional colours).

What Makes Cotman Paints Student-Grade?

Cotman watercolours contain less pigment and more fillers compared to artist grade paints. This different formula creates a slightly chalky feel that you’ll notice immediately if you’ve used professional paints before.

The Cotman line focuses heavily on hues rather than pure pigments. You get cadmium yellow hue instead of true cadmium – synthetic alternatives that keep costs down but don’t quite match the intensity of expensive pigment colours.

Key differences:

• Less pigmented and less vibrant than artist-grade paints
• You need more paint to achieve the same intensity
• Colours appear lighter and sometimes chalky
• Still includes pigment information on packaging (uncommon for student paints!)

The Cotman Pocket Box: Portable Option

The Cotman watercolour set comes in various formats, but the pocket box is particularly popular. It’s genuinely tiny – fits easily into an average-sized pocket or any bag.

What’s included:

The half pan set typically contains 12 Cotman watercolours:

• Cadmium Yellow Pale Hue
• Cadmium Yellow Hue
• Cadmium Red Pale Hue
• Alizarin Crimson Hue
• Cobalt Blue Hue
• Ultramarine Blue
• Viridian Green (or Viridian Hue)
• Sap Green
• Yellow Ochre
• Burnt Sienna
• Burnt Umber
• Chinese White

The set includes a little brush that fits inside the case (though it’s honestly quite short and overly round for detailed work). Multiple mixing palettes stack within the compact case, and each half pan comes individually wrapped with pigment information.

Performance: How Do Cotman Paints Actually Work?

For Beginners

The Cotman set is genuinely beginner-friendly. The paints mix and blend well together, making them suitable for learning basic watercolour techniques and colour theory. The individually wrapped half pans help you learn about different pigments from day one.

The secure closure means you won’t lose paints during transport, and the stacking mixing palettes give you decent space for experimentation. It’s a solid starter kit that removes the guesswork from choosing art supplies.

For Experienced Artists

Here’s where things get trickier. The slightly chalky texture can affect blending smoothness for layers, and the limited vibrancy means you’ll struggle with detailed, layered painting styles. The compact mixing palettes restrict space for complex colour blending too.

Cotman paints work best for sketching styles that don’t require heavy layering. They’re brilliant for quick studies and loose, expressive work, but less suitable for advanced techniques like glazing where you need transparent layers to work together perfectly.

Common Complaints

• No purple shades included (mixing purples is particularly difficult)
• Chinese White takes up one slot, effectively reducing usable colours to 11
• The little brush is too short and round for versatile work
• Earth tones can feel student-quality even by student-grade standards
• You need more product to achieve intensity, potentially offsetting cost savings

Value: Student Grade vs Professional Grade

The Cotman watercolour set typically retails around £35 on Amazon UK, though Australian art stores charge over $80 AUD (making it quite overpriced in some regions).

Compared to professional watercolour:

• Colour intensity: Much lighter, requires more brushwork
• Visual appearance: Can appear chalky vs professional’s smooth finish
• Mixing capabilities: Limited, especially for vibrant greens
• Layering: Basic layering possible but restricted
• Cost: Significantly cheaper upfront
• Value: Better for beginners; professionals will find it limiting

Other Winsor & Newton Watercolour Products Worth Knowing

Half Pans vs Tubes

Winsor & Newton offers their professional line in both tube paints and half pans (also whole pans). Here’s the difference:

Tubes:

• Fresh paint ready to squeeze
• Great for larger washes and bold colour application
• More economical for heavy users
• Easy to fill empty pans if you prefer palette setup

Half Pans:

• More portable and compact
• Less messy than tubes
• Perfect for travel and plein air painting
• Re-wet easily with a water brush

I’ve used both formats, and honestly, it comes down to personal preference and how you paint. For studio work with larger pieces, tubes are brilliant. For sketching outdoors or travelling, half pans win every time.

Additional Tools and Accessories

Winsor & Newton doesn’t just do paints. Their range includes:

• Tools brushes – Various sizes and shapes for different techniques
• Watercolor paper – Professional canvas and media paper options
• Graphic markers – For mixed media work
• Ink sets – Drawing and calligraphy inks (currently 20% off!)
• Little sponges – For texture and blending

They also offer promotional sets and back gifts during certain periods, which can provide excellent value.

Free Delivery and Returns

• Free standard delivery on orders over £59
• Free next-day delivery on orders over £75 (if ordered before 4pm)
• Easy returns quality – Newton satisfaction guarantee backs all products
• Orders typically dispatch within 1-2 business days
• The return process is straightforward and customer-friendly

Safety and Compliance

All Winsor & Newton products conform to safety standards:

• Product conforms to federal regulation requirements
• Follows labelling of hazardous art materials regulation
• Approved by Artists Craft Material Institute
• Doesn’t pose chronic health hazards to users
• Safe for both beginners and professional artists

My Personal Experience: Which Should You Choose?

I’ve personally used the Winsor & Newton Professional Watercolour tubes, and here’s my honest take based on my journey:

My experience: I started with a cheap 50-colour set from Amazon (which was brilliant for experimentation and figuring out what colours I actually liked). Then I invested in Winsor & Newton Professional tubes – specifically Mars Black, Sap Green, Prussian Blue, Ultramarine Violet, Scarlet Lake, Opera Rose, Green Gold, and Lemon Yellow Deep.

The jump from that cheap Amazon set to professional watercolour was genuinely noticeable. The difference in quality, vibrancy, and how the paints behave is significant. For me, it was absolutely worth the investment once I knew I was committed to watercolour.

I’d recommend:

Start with an affordable set if:

• You’re brand new to watercolour
• You’re not sure if you’ll stick with painting long-term
• You want to experiment with lots of colours to find what you like
• Budget is a major concern

Invest in Professional (like I did) if:

• You’ve tried watercolour with a basic set and know you love it
• You’re ready to commit to quality paints
• You need colours that mix cleanly and stay vibrant
• You’re creating work you want to last

I don’t regret starting with that cheap Amazon set – it taught me which colours I gravitated towards and helped me make informed choices when I upgraded. But now I use Winsor & Newton Professional exclusively, and the quality difference makes painting so much more enjoyable.

Alternative Options to Consider

If you’re exploring watercolor sets beyond Winsor & Newton:

Daniel Smith Watercolors – Excellent professional alternative, huge range

Schmincke – Often better value than W&N professional

M. Graham – Honey-based formula, rich colours, generally less expensive

Each brand has its strengths, and I’d encourage trying a few different options once you’re past the absolute beginner stage.

Final Thoughts: The Joy of Watercolour

Choosing between professional watercolour and student grade paints ultimately depends on where you are in your artistic journey. From my experience, starting with an affordable set is a smart move – you learn the basics and figure out what colours you actually use without the pressure of “wasting” expensive paints.

The Cotman range (which I haven’t personally used but is highly regarded) provides an accessible way to discover the joy of watercolour as a step up from basic Amazon sets. The professional line delivers the performance and quality that I’ve come to rely on in my painting.

The two tube sets I’ve focused on here (the Winsor Set and Rich Earth Set) represent excellent options within the professional range. Based on what I’ve learned from using professional watercolours, the Winsor Set would give you versatile primaries for clean mixing, whilst the Rich Earth Set caters to those who love natural, earthy tones.

I made the jump from a cheap Amazon set straight to Winsor & Newton Professional tubes, and whilst that worked for me because I knew I was committed, there’s no shame in taking a more gradual approach through student-grade paints first.

Whichever path you choose, Winsor & Newton’s reputation for good quality is well-deserved. Just shop around for the best prices, watch for promotions, and invest when you’re ready.

Now, if you’ll excuse me, I’ve got some Prussian Blue calling my name.
