If you are trying to mix watercolours and the colour is not quite right so you add a little bit more colour ending up with a lovely mud colour, this Winsor & Newton book is for you. The 25 main colours used from the Winsor & Newton Artists' Watercolurs gives 2400 two-colour mixes. With only mixing two colours you get the cleanest and brightest tints possible, this makes it easy to match the shade you want to reproduce. The colurs included in many Winsor & Newton pre-selected painting boxes are featured in the 25 main colours used.
Overall, excellent book, great value for money, I wish I had bought it when I first started painting. I would have probally saved myself a lot of money on buying colours I probally will have little use of.
Please note: The book does state that all mixes are made with Winsor & Newton colours; colours by other manufacturers will give varying results.
