So I was playing around with digital painting in the CMYKA colorspace, since I kind of liked that it gave kind of a more naturalistic color palette than RGBA, especially when going for more “rainbow-ey” tones.
I ran into the problem that none of the blending modes (multiply, color dodge etc.) do what I want them to when they are changing CMYK values, but did read something that Krita supports layer by layer color spaces. So I was going to try doing a CMYK painting layer in a RGBA image and apply blending effects in other layers, but I can’t seem to figure out how to do this.
The documentation seems to indicate that there should be a convert->convert layer color space in the layers menu, but I’m not finding it. The properties menu for a layer lists the color space but will not let me change it. I’m currently using Krita 4.3, but had no luck with my Krita 5 beta build either.
Is there a setting I need to change to let me do this?
@TheTwo I don’t really understand blending modes vs colour space.
I do know that some blending modes are not available with some colour spaces and this is indicated by a special icon for a particular blending mode which is shown if you create an image with CMYK/A colour space.
However, if you have an image created in RGB/A colour space, then convert one of its layers to CMYK/A, that icon is not shown in the blending modes lists for that layer.
Using LAB in the RGB color space does have better color mixing. But everything is gray in Gray space…
It seems that when it is displayed, it has been converted
They work exactly opposite of how they work in rgb since CMYK is subtractive color. I think there was some bug report to make it show opposite to be consistent like how other software show.
