This isn't quite done yet, and I need to push out a bunch of Iron Maiden mods before I finish this up, but it should give you an idea of what will soon be possible to fix the stark white X-Men insert lighting. Since there are so many areas, I'm going to offer it as 4 mods:
1. A mode light bracket for the mode lights
2. A "Shoot Again" bracket to make it the traditional orange
3. A set of color-coded brackets for the rectangular character inserts
4. An X-wheel bracket that colorizes the characters on the X-wheel so they match the colored inserts.
Here's what they look like with all of them installed:
