Why yes, this has been suggested before.
But seriously, why not? What does it hurt?
Our prismatic colors blending in with the background? The colors of enemies blend in with backgrounds already, and everyone has been putting up with it.
That's a check off the list. I can't see any other problems.
So why not have a few yellow dashing and pink shield bashing? < - Examples.
""If you can change the option to turn it on/off, sure.""
What everyone else said. I actually wouldn't mind if it wasn't an option either, because there's no trade-off with this. An option wouldn't hurt though.
Make it purchaseable from the SD or Featured Auctions or a Mirrored Lockbox.
Actually, the toggle option doesn't sound too bad at all. It can be used if you hate gross colors or just love cyan colors, since there isn't any levels that are of the cyan color. (Freeze themed areas on the ground where dashing and bashing count are blue/dark blue)
Originally wanted this to be free as dashing, bashing, and the color of your knights are not paid for when you start your character.
But the payout for purchasing one of these could be an rare personal cosmetic item, much like how eyes and extra modifiers are. Dont know which one OOO will choose if they ever went with this suggestion though.
If you can change the option to turn it on/off, sure.
