Describe the feature you have in mind.

Create 0.6 added 2 new dyed blocks, those being the Table Cloths and Postboxes, these are missing in the current version of the mod.

Does this solve a particular problem?

Yes, it solves a lack of parity with the vanilla dyes that has been created by the new Create mod update.

on it, btw it's create 6.0 not 0.6

Since this mod also adds support for Create Deco and Create Steam & Rails and neither of them currently support create 6.0, this might have to wait until they do
