Can we get more variance in dye colors? Darker darks and lighter lights?

For a lot of the dyes, the difference between light, normal, and dark isn't all that great. For many of the colors we have a real issue with darks. Dark Green for example is extremely vibrant and bright green. It isn't very dark at all! I would create new dyes rather than change existing ones, but it seems like it should be an easy win to add new flat colors for the palette?

 

i think part of this is that they have inconsistent effects on different pieces of clothing. the same dye can be almost black on one thing and almost neon on another.

 

I'm gonna need more plain white carnival masks.
