It will be very good if You add multicolor (all colors) palette for 100-200 white/black pearls in pearl shop.

When you crafted or bought a costume for the first look you can choose what colors to apply on it or leave in original.

Also its good to add 4 color palette crafting using different loot from killing mobs or synthesis to change color.

Or at least synthesize specific numbers of 3 color palette to get 4 color palette that you need.
