Cathy Pearce Colour Wheel 18 Small Stick Soft Pastel Set

The aim of the colour wheel set is to help you learn the basics of colour theory.

Pastel Size GuideShare Your Experience

£97.99

The aim of the colour wheel set is actually to help you learn the basics of colour theory and not as an ultimate set of colours with which to paint every picture. As you will probably already have experienced although you can change a colour, it’s very easy in this medium to make a colour more dull, it is very difficult, in fact impossible, to make a colour brighter. With this in mind this set of colours also gives you the bright, saturated version of the main colours which will be a really useful accompaniment to your existing pastel collection. The black, white and four greys will allow you to make tonal sketches in advance of your paintings in order to achieve all the correct tonal values when choosing your final palette.

  • Blendable

    Our pastels have superior blending capabilities, whether combining colours or layering.

  • Lightfast

    Your paintings will shine for years to come with the best rated pigments.

  • Mixed Media

    Use our pastels in conjunction with watercolour and acrylic, or in any other creative ways.

  • Soft and Smooth

    ‘Just like butter’ – Our pastels need no encouragement to leave their mark.

  • Highly Pigmented

    Using the best pigments to provide the deepest colouration for your work.

  • Flexible

    Use wet or dry on the broadest range of surface types.

Recently ordered the Autumn Rains set. Rec’d fairly quickly and was packaged well. Just started using the set, and really like them. Very easy to work with, nicely blendable, good coverage. Colors in the set are just beautiful. Am enjoying using them!

My first order online of Unison, love the personal assist, Oliver and Dan, thank you. And of course loved the colours :)
I am fairly new to pastels, and have tried few, but when I tried Unison, that was it! The pigment is so good, and to work with them really good. So I am now a Unison fan :)

I ordered the hand made colour charts from Unison. What arrived was a wonderful set of hand made colour charts for each of the colour ranges each coated in a clear covering to preserve the pastel. Each chart is titled with the colour range (e.g. blue violet, red earth) and each colour is numbered. The set comes in a box which also helps to preserve the charts.

I m very grateful to have found the Unison Pastel online store because in our country, Georgia, there is a limited selection of pastels. The quality of there pastels is outstanding, with soft gradations. it is convenient to be able to order individually and also in interesting combinations. The delivery is also of high quality. Thank you for helping artists in this way.

So I've bought, the mini sets Centenary, Drawing Spring, Winter and Summer Dazzle and some pastel paper. Unison's website very easy to manage/navigate. One thing went wrong, but they were on it and dealt with it very very quickly - thank you Oliver. I've always wanted Unison pastels as they get such good write ups. I haven't been disappointed. Every set is brilliant, so well curated but Summer Dazzle is just sublime. Before this I'd bought Autumn mini set, 36 stick Landscape and Midnight. Midnight is just gorgeous, especially the blue sticks. I haven't tried the paper yet but I'm so glad it's in conjunction with Two Rivers, my favourite paper company. Anyway, playtime now...sorry I meant pastel painting time.

I reunited with Unison a few years ago. I have them stored beside my easel and many of my pastel paintings are 70% and up done with Unison. They have become my favorites.

I had been working on the painting below and I just was not able to achieve the brightness in the center of the painting that I wanted. I wanted something with a some sparkle to it. I received an email from Unison and saw Summer Sparkle Mini set and there was my color with the sparkle.! When they arrived I went to the easel and finished my painting."Blue Bells On Campus". And the packaging with this mini set tops the set off with a glittering band. I love this set.
Art always makes me happy but this mini set really made my day. Thank you so much. Donna Housel

Unison Color soft pastels are the Rolls-Royce among the different pastel brands I know. Some qualifiers: good hold of the chalks, tenderness of the powder, intensity and brightness of the colors. A real joy to work with.
The family business is very professional. Recently I ordered their color chart and a box of colors and I was served quickly and efficiently.

Beautiful pastel set, I have a set of hard pastels which I enjoy working with so I'm going to look into the Unison pastel training to make the most of these soft sticks.

I recently bought both the Autumn and Winter Mini Sets from Unison Colour. The colours are absolutely stunning in both Sets. Although, I haven't used the Winter set, yet, I have used the Autumn set in the Autumn landscape image. The pastels are perfect in colour, size, their smoothness and are just beautiful. Quality at its best. I can highly recommend Unison Colour, overall.

5 day pastel challenge was a well designed forum for skill refresher, opportunity to receive helpful feedback and discussion. Stephen Fuller conducted the series beautifully, gave helpful tips, listed the specific tools and pastels he used (while encouraging use of substitutes if you were lacking those).

The Unison 'Autumn Rains' pastel challenge with artist Stephen Fuller was just excellent. The piece was beautiful, the tuition well-delivered and well-paced, and the feedback was amazing. Stephen generously took the time to do live questions each evening and, incredibly, put an encouraging comment on each picture that participants posted in the Facebook group. He's a lovely man to learn from, and his art is gorgeous. Thanks Stephen and thanks Unison for arranging this. I love your pastels and your associated artists!

These soft pastels came to me expertly sustainably packed.
The pigment and binding medium are very high quality and represent all-round good value. I liked the presentation .. boxes that are strong and nicely designed quite adequate for fieldwork.
My choice of pastel reflects my style and personal preference. The pastel are a joy to use thanks.

Purchased a couple of single colour pastels to supplement the set I had previously bought. I love unison pastels as they are very soft and blendable but also have fantastic depth of colour. The pastels arrived quickly and were very well packaged. Communication with Unison is great - they really care about the products and their customers.

Unison pastels come in such a huge range of vibrant colours. I chose them initially because they are British made having previously tried other brands originating elsewhere. I soon fell in love with them. I am a beginner but I find them easy to use and their layering qualities are much greater than others I have tried. Turn round time on orders is quick and the products are well packaged.

The Unison community of users and artists is very friendly and so helpful and supportive of a beginner like me. The pictures below show the vibrancy of the colours.

Unisons 5 day challenges are amazing. They are hosted by unison associate artists and are completely free. I have completed several. You learn lots of new techniques and get to be part of an amazing community of artists. Thank you Unison.

I initially purchased the hand drawn colour chart so that I could try and match my pastels (of varying makes) already having a few unison pastels I decided to also purchase the set for The Haven 1 day course after completing the 5 day Durdle Door challenge, which I really enjoyed. Just love these pastels as they are so soft and creamy and blend really well. A great course with excellent tutor Nina Squires and Dan and the Unison team. Very professional with excellent handouts and all questions answered in the Q&A's.
Can't recommend them enough to anyone to try these courses they are brilliant and with unison and the fb community with you all the way encouraging each other, it really gives everyone a boost.

Colour Chart Guidance

We believe the colours in our web based colour chart are a faithful representation of our pastel range. But with any colours portrayed on the internet, there’s a whole heap of variables which mean that what you see, may not be what we see. That said, there’s some things that can be done to mitigate some of the variance.

Mobile phone and tablet screens tend to be pretty good for colour, so they’re always worth using, when viewing our colour chart.

We hate to say it, but cheaper computer displays, including laptops, can be rather hit and miss, in both colour and contrast, so they might not reveal the depth of the colour, as well as the true tone.

If you’re really keen on getting your computer up to speed on colour representation, you can use a calibration device to reach your display's fullest potential.

With all that said, if you think we’re way off the mark with any of the colours then, by all means let us know, and we’ll give it another shot.

Please do bear in mind that our pastels are hand made from a variety of traditional pigments, all of which have their own characteristics. This means that size does fluctuate ever so slightly, and the softness varies between the different colours. We do, of course, keep well within our criteria for the perfect pastel, but if the pastels you’ve received don’t quite live up to your expectations, please get in touch and we’ll make sure it’s put right.
