COLORS interface is unnecessarily difficult to work with.

[GeorgeMuscat]

The COLORS interface is difficult to work with and many QoL improvements could be made.

Have the 16 colors represented by a static array of structs is code that is not self describing and requires documentation consultation to understand which color is which.

Additionally, the static array can only be indexed using a usize, which is an unnecessary constraint and helper interfaces can be implemented to improve the user experience.
