Hello,

i know it is only RGB.
But the colors are display togehter, so in i can see other colors, like Yellow, Purple, (Black).

The Color_Deconvolution Plugin can already do this, it does split by every 3 colors i want.

My problem is:
I have a picture (scan) with circles in different colors (up to 10 colors). I want to know the area of every color, so for example all red circles include an area of 10mm^2.
But i have to split the image to only measure one color.


Michael.
