This is what I have:
while true do game.Players.LocalPlayer.findFirstChild("Body Colors").HeadColor.Color = Color3.new("Bright blue") end
Is that trying to change all players head color?
Well, you would do something along the lines of this in a local script:
local player = game.Players.LocalPlayer local char = player.Character char.Head.BrickColor = BrickColor.new("COLOR HERE")
