Role Color expansion?

Considering some people find Nitro/Server Boosting a bit too plain still, I thought that perhaps another feature that could be added would be that server boosting allows the administration to make role colors that are different colors. For example, something like a role color could be split in half at one point to change into another color, or the role color could be some sort of pearlescent shade. 

For Nitro, perhaps there could even be something like a "Persistent" role color they can set that's universal and overlaps server colors(this can be turned off, both on the user and admin side).
