Leather Armor worn by hostile mobs should be randomly dyed

When a Zombie, Skeleton, Drowned or any other mob spawns with leather armor, the armor should be randomly dyed. Perhaps this could also have some level of rarity, most leather pieces could have muted gray-brown colors but on occasion they could be more vivid and saturated. This is a purely cosmetic change but I feel like dyeing leather armor is a very underutilized mechanic and it would add a lot of flavor to the game. Additionally I think it would be nice if there was a pretty high chance (50%?) that a mob could have two or more pieces in the same color, to kind of color match. Perhaps that was their favorite color in their past life, or maybe that was the fashion at the time?...
