Color Coded UI Buttons for Accessibility

I have very poor vision. While making the UI bigger absolutely helps, having color-coded buttons would be a game-changer for me. Not in the sense of a new UI theme, but rather that particularly important UI icons have a unique color. For example, the manage world button could be blue and the shop button next to it could be orange. I imagine this could help other players as well. It could even be a toggle on/off option.
