Colour matters – colour comparison tip
based on Winsor & Newton professional watercolours
From today, each month, I will be making a short blog about Winsor & Newton watercolour pigments and explain a few discoveries I have made along the way. Each blog will contain a range of interesting facts, tips and tricks. It will be a monthly post at about the same time each month, so look out for it around the 24th!

Alizarin Crimson versus Permanent Carmine…
Is Alizarin Crimson dulling your paintings? It looks really bright in the palette so why should this be? Don’t you wish it would stay bright?… well, unfortunately, that’s not possible as it will always dry a little duller than expected. This is because Alizarin Crimson (PR83) is a warm red with a slight maroon bias. It is also fugitive and will fade in sunlight. If you like to use Alizarin Crimson then make sure you buy the permanent version, Permanent Alizarin Crimson (PR206) for reliability.
Another question springs to mind. What’s the difference between Alizarin Crimson and Permanent Alizarin Crimson? There is very little difference in colour but Permanent Alizarin Crimson is very permanent, rated ‘A’ so shouldn’t fade. Alizarin Crimson is moderately permanent, rated ‘B’ and fugitive so it will fade badly. Alizarin Crimson is not good to use if you are exhibiting paintings where reliability and permanence are expected. An ‘A’ rating is always much better!
You could substitute this colour for Permanent Carmine (Quinacridone pyrrolidone) which is only a teensy, tiny bit cooler. Add a teensy, tiny bit of Transparent yellow to it and you’ll have a Permanent Alizarin Crimson match which stays bright. It will also give a slightly brighter colour mix when added to yellows and blues. Add French Ultramarine for a beautiful rich warm purple/mauve. Add Indian Yellow for really rich and vibrant orange and red mixes. Historically, Carmine was made from thousands of crushed kermes insects, ewwww… Thank goodness for Quinacridones!
Until next months, take care and keep safe!
Look out for my book ‘ Watercolour Mixing Techniques for Botanical Artists’ coming out later this year!
