A Few Notes
Q: Corals?
A: Yes. Bonemeal the ocean floors and enjoy. Check the wiki.
Q: Will this work with Ordana's Logical Dye Mixing?
A: It should. There's one overlapping recipe, though, but it shouldn't be a problem (the result is the same).

Mod suggestion: Pandarix' Bushier Flowers (because it makes harvesting dyes much easier. Also it looks pretty cool.)
Tested with Fabric API 0.92.0+1.20.1
This mod is provided "as is". It should technically work on all 1.20.X versions of the game. I am not planning to update/backport this mod to a different version of Minecraft. You're free to do so yourself, however.
