Annotating colors in BLI_color.hh with the goal that it becomes more clear in the code what color and alpha association is used.
- Changes to BLI_color.h + migration of existing code (Function + Geometry nodes): D10978: Blenlib: Explicit Colors.
- Compostor: Is already CPP and some operations use color space conversions.
- Color picker: There is an effort to move more UI code to CPP Color picker is one that would benefit in readability.
- Draw manager: Although this is in limited places.
- Blenkernel: blenkernel (colorband, gpencil, image_gen, studiolight) seems like small tweaks.
