[REQUEST] RGB energy color?

[Fiedra]

Listen. I can already hear Steve screaming in pain. But as a rainbow fan, I HAVE to express this request.
How about a special, animated rainbow emissive/energy color for people who achieve Legend MR?
This could be implemented in a lot of ways besides that, like putting an archon shard of every color on a warframe, which could potentially take some time and skill to achieve, which would make it not appear everywhere. It could also be a supremely rare Peculiar Mod, requiring a mod slot to be sacrificed in order to use it which would make most people shy away from it as well. But the hardcore rainbow fans would be eating good.

only if it plays caramelldansen from the next tile over whenever you have an ability active.

There is a Shader in D2 that does this, but others have a pulse effect like its broken

Also may I add an "invisible choice". What I mean: choosing black as energy colour in some cases looks as a "no colour / invisible energy" and in other cases as "black energy / dark matte effect". There should be a separate button for the invisible, while choosing the black colour shall make the later effect.
