Wool-Concrete…spansion…World of color, part two

Personally, I feel like wool and concrete are outdated colorwise just because there's such a disconnect between so many colors. You can't see how cyan goes into light blue that goes into dark blue or how cyan goes into dark green, which goes into lime and don't reflect the current uniqueness and complexities of other builds which is why my suggestion is adding a few more colors i need my Violet, Indigo, Navy, Teal, Aquamarine, Turquoise, Chartreuse, Tangerine, Amber, Vermilion, Rose as well as Pastels. I feel like it is only appropriate to do it in these concrete and or wool because a lot of these colors do not naturally occur, especially in other biomes unless it's a unique world like the end. It makes absolutely no sense why you can't have the same complexities of leather armor to your blocks.
