Team colour mismatches in the minimap

So whenever I 3v3 or 4v4, I've noticed that the team unit colour and the minimap colour often don't match. Someone will say "hey Red, attack coming" and it'll take awhile to realize who they're talking to because I show up as green on the minimap.

Is there a way to force it to always match these colours? I really don't see why it doesn't already do that, but I may have just missed some essential setting.

Did I? Or is this just bad design?
