Question

How can I set percentage values (0% to 100%) on CYMK format instead of default values (0 to 255)?

Currently full ink black color is:

Image.new("CMYK", (width, height), (0, 0, 0, 255))

I want:

Image.new("CMYK", (width, height), (0, 0, 0, 100))

Answer 1

I see here that for RGB, you can specify in percentages.

RGB functions, given as “rgb(red, green, blue)” where the colour values are integers in the range 0 to 255. Alternatively, the color values can be given as three percentages (0% to 100%). For example, “rgb(255,0,0)” and “rgb(100%,0%,0%)” both specify pure red.

Can you also try this for CMYK?
