A Fix To Not Having Perfect Colors In Builds

Lets say that you have a build in progress, and you need a textureless (solid color with no type of design on it) block. Much like when you build skin statues or block portraits. You scour every possible method with every possible block only to realize that the perfect colored block simply does not exist. Your build quality is greatly diminished, and you cannot have the satisfying end result you truly deserve for your hard work. 

The fix that I would HIGHLY suggest, make a block (obtainable in survival) that you can assign a Hex color code to. This way it is even less possible to find that EXACT color you need for perfection. I'm sure that various builders have experienced the same frustration that I am now.
