Improve color inspector

Summary:
Before this change, color inspector used a color picker that showed: color, rgba, hex.

The problem is that engineers have to click on it to see these values.

This change leaves the picker as is, but presents both hex and rgba inlined within the inspector thus avoiding extra interactions.
