3 feature requests regarding color consistency:
Copying colors in C4D can me made more easy by adding Copy/Paste in the contextual menu (right mouse button).
Add the Quickstorage thing to every spot where Colors can be entered. (e.g. the Diffusion channel / Texture/Color)
Maybe the best solution: add a colour swatches palette that can be accessed always (and Saved in the Conten browser!).
