Steps to reproduce:
1. Color any piece of armor, to any color.
2. Notice that in your hotbar, the armor is not colored, but it is colored in your hand.
3. Tap inventory button.
4. Notice the armor displayed in both hotbar and inventory is now colored.
I did search to find this issue and did not find any results.
