Dyable Item Frames?

-There is another suggestion about this but it doesn't explain why-

• An item frame is crafted with 1 leather and 8 sticks. As we all know leather armor is dyable, so why shouldn't the leather of the item frame be too?
• The other block that can be dyed with a glow ink sack is a (hanging) sign and these can also be dyed so why not be able to dye a frame too?
• I think being able to dye a glow item frame would be epic, since the colors would be more vibrant and the glow item frame itself would look nicer in storage systems/shops, since we cant change the wooden frame.

It would be a very simple yet very appreciated addition to the game, not to mention that feels like it was already a thing. I would love to see a way Mojang could make it different than we imagine, but sometimes simple just fits the game-> combine dye+frame in crafting table, done.
