These fill gaps in the dark purple-black, green, grey, orange-red and bright orange ranges, providing colour references for previously difficult to match plants including Dahlia, Chrysanthemum and Iris in particular. The colours are arranged in 4 easy to use fans and each colour patch has a central porthole which can be laid over the object under being matched; The fans are supplied with full instructions in 6 languages. The RHS Colour Chart is the standard reference for plant colour identification and is indispensable to gardeners and breeders who value the accuracy in identification of plant colours.
