How do we STILL NOT HAVE A SOLID BLACK/WHITE/GREY COLOR PAINT PATTERN (1 of each)

Like so many times I want a solid color on something and have to settle for tiny parts being the other colors unless it’s either black (Apolyon) or white (frostwind event color)

It is such an easy thing to implement….. and would be much easier than making every color get a pallate where all 3 sections are the same color
