FIMO soft standard blocks are segmented into 8 portions, making it very easy to blend the colours. 

Use the blending table to help create the colour you require. E.g. by blending 3 parts yellow (-10) with 5 parts pink (-22) you get a warm red colour.

It's just as easy to make colours lighter or darker - all you have to do is to add black (-9) or white (-0).

Actual colours may differ slightly!
