Update the Map item by assigning new Colors to existing Blocks

Currently, there are various blocks that share colors when viewed through the Map item. For most of them, I understand why. But for others, not so much. One example of this is Sand, Birch items and End Stone items sharing the same color. I would like to suggest that certain blocks with the same map color should be separated, and given new colors. This will make structures more identifiable, make maps more colorful, and will give map artists a broader palette to work with, which is a nice bonus. Here are the ways to go about that:

Here are the blocks that I think should be separated: Birch items, End Stone items, Bone Blocks, and Scaffolding from the Sand color, Grass Path and Granite from the Dirt color, Red Sand/Sandstone and Honey + Honeycomb Blocks from the Orange color, Crimson items and Nether Brick items from the Nether color, Blue Ice from the Ice color, Purpur items from the Magenta color, Warped stuff from the Cyan color, and Mycelium from the Purple color. All of these separated blocks should then have their own new, unique colors.

I also have some extra block map color changes that I would like to have but aren't necessary. The Cauldron, Anvil and Hopper could be taken from their origin colors and merged into a single new color. Kelp could be moved from the Green color to the Green Terracotta color since it makes more sense. And finally, all Concrete and Glazed Terracotta blocks could be removed from their respective colors and be given new ones.
