</div>colorspaces can convert the pixels from another colorspace to their own before doing composition, but for painting on masks that's not currently useful since we generate dabs in the target colorspace anyway.<br>

The real issue is not the conversion, but that krita cannot handle colorspaces without an alpha channel -- or colorspaces with alpha pre-multiplied, which this would be, I guess. This is, I think, a limitation that permeates Krita everywhere.<br>

For 2.4, it's certainly not something I see feasible to implement. Nor am I confident it would be a good idea: it was a conscious design decision back then. It's why we always have cmyka, never just cmyk.</blockquote>
