Doflamingo used it on his stings, it might have the same effect he weponized the 'red', sorry for butting in.

I figured that'd be the case. I was curious as to whether or not the object would need to be visually identifiable as "red" in order to maintain the power. At the end of the day, it's still technically red, even under the hardening effect of Armament Haki, I'd guess.
