Should "rainbow hair" imply "multicolored hair"?

Title is self-explanatory.
 
I was wondering if rainbow hair should have multicolored hair added as one of it’s implications, since characters with rainbow hair would have a lot of colors in their manes, and I though it’d make sense for that tag to be added in.

Sure. I don’t see why it shouldn’t.
 
My only concern is the majority of the rainbow hair posts aren’t actually tagged with multicolored hair. Means it’s likely they have been kept separate for a reason. Not sure if that reason is a good one but it’s worth mentioning.

I think its because people either forgot to add in that tag, or they didn’t know about it.
 
Anyway, should the tag be implied now?
