Classic star colors

[Askaniy]

I suggest

• rename them to "Legacy star colors", I think it's a more appropriate name
  or
• just remove them; they are unreliable and may be misleading

Perhaps a discussion is needed.

I'm in support of removing them completely (and I believe at this point I know how to remove it) though if this is, for whatever reason, not an option, I support action to rename it to legacy.
