Description Raghavendra kamath 2014-10-17 20:35:28 UTC

Current specific color selector has input field from 0-255 for CMYK.
Most of the print design work requires artist to have values such as C=10 M=20 Y=100 K=80 etc.
these values are in percentages.

I request a way to input the values in percentages, as now we have manually calculate the values for accurate colors in CMYK which is time consuming.

thank you

Reproducible: Always

This is problematic, actually... We really need to figure out how this fits with the way lcms2 works.

Me too went into this problem today. I have a book about traditional Chinese color, it's so _traditional_ that it only supplies CYMK values without RGB. And yes it's in percentage (I never used CMYK so I learned that fact today myself). I have to use an online CMYK to RGB converter before I can use the colors in Krita. 

An small inconvenience that rarely matter, I suppose. It would be nice if we could just auto convert the input value internally from 0-100% to 0-255 in the Specific Color Selector.

Thank you Boud!

By the way Will this work for all color models? 

There is a funny story here: I have yet another traditional color research book that was "so serious" about their research they got their color values NOT FROM A COLORIMETER/SPECTROMETER but FROM A DIGITAL CAMERA's JPGs and PICKED UP THE VALUES IN PHOTOSHOP), while using CIE L*a*b only in their book...it happened right after I read that CMYK only one and I was speechless. I guess they felt really professional about all that. XD

Except for the floating point colorspaces, yes, I think.
