Ok here we go
I add 2 hex values. It all works well ... and then i try to add blue(#0000FF) and yellow(#FFFF00) which should give me green right?
Well no After the addition i get white(#FFFFFF).

Same happens if i add RGB values seperate as Red, Green and Blue or as a whole number.

How whould i be able to mix, add blue and yellow together without getting white?

So now i want to try with CMYK values.
Can anyone please tell me how to convert Hex/RGB values to CMYK and reverse?

Thanks
