How would the scratchpad docker work with the multi-channel spectral color blending feature to emulate CMYK blending? Hopefully such a feature could be used to facilitate color blending for artists used to blending colors on a paint palette. I have discussed this potential on another thread in this forum ([CMYK Color Blending Mode](https://krita-artists.org/t/cmyk-color-blending-mode/6152/9)). I have also discussed the possibility of using the mixer palette to facilitate the loading of color gradients on a brush tip in yet another thread ([Feature request: to use two or more colors at the same time at the same brush tip](https://krita-artists.org/t/feature-request-to-use-two-or-more-colors-at-the-same-time-at-the-same-brush-tip/5543)); however, other methods of multi-color loading onto brush heads were also discussed there, such as creating a separate brush engine or modifying the clone brush engine. --- _[View the full topic](https://krita-artists.org/t/scratchpad-docker/3132)._
