Book excerpt: For more than 200 years the world has accepted that red, yellow and blue - the artists primaries - give new colours when mised. And for more than 200 years artists have been struggling to mix colours on this basis. In this exciting new book, Michael Wilcox offers a total reassessment of the principles underlying colour mixing. It is the first major break-away from the traditional and limited concepts that have caused painters and others who work with colour so many problems. Back Cover.
