I'm sure other people have had this idea, and I'm just wondering if it's possible. I don't really consider this a request, but I figure it belongs here just to discuss.
A colorset that is universal, meaning it has the whole spectrum of colors that is adjustable, but isn't limited to 64 colors. For example, if I were to place a ghost brick, I could set it to whatever color I wanted, and it would save as that specific color. You could save the colors as a set as well, but for the most part, there would be no limit. Get what I mean?
