Secondary base skin color - white/grey

This just came to my mind as it always bothered me that rare skins sometimes/or every time look so bad especially with the black base color of the skin.

How about adding a different color than black you could choose for your weapon that would be used for the parts where common, rare and even some epic skins are black rn. Some colors that would work great would be white or grey.
This would be an amazing way to make some of those skins more interesting while at the same time not changing anything about skin rarity while still giving people more customization for the skins that dont look good with black.

Could as well just make it per skin and not per weapon. This way you could make use of legendary tokens (credits for those that dont have any) for a semi permanent change of skin color (secondary color) until they change it again.
Might also work to introduce some more expensive and better base colors than rare then which would defenitely spice up things a lot imo.
