I have a geological units shapefile which has colour data in a field, in which the colour data relates to an associated text and will help in clarifying which unit is which down the line. An example is: "BASECOLOUR" !FIELD NAME "40, 15, 5, 0" !FIELD DATA
I assume these are CMYK values?
So, how can I do it? Can I build a rule-based expression which uses the field to define the CMYK values?
