Feature description:

Allow the user to right-click on any grid with a colored dye, and be able to change the color of any kind of grid to one of the 16 colors, so it can fit with the aesthetic of a room, for example.

Version (make sure you are on the latest version before reporting):

• Minecraft: 1.10.2
• Refined Storage: 1.2.26

I apologize in advance if this has already been added in a 1.11 or 1.12 release, this post will be deleted promptly if that is the case.

No.

Any particular reason?

Maybe more important things to do? If you really want it codes are here at the open. Do it yourself.
