This script does not work.
while true do local v=script.Parent wait() local a=v.R1.BackgroundColor3 a=Color3.random() wait() v.R2.BackgroundColor3=a v.R3.BackgroundColor3=a v.R4.BackgroundColor3=a end
You can't do Color3.Random() instead you can do:
while true do local v = script.Parent local num = math.random(0,255) local num2 = math.random(0,255) local num3 = math.random(0,255) wait() local a = v.R1 a.BackgroundColor3 = Color3.new(num/255,num2/255,num3/255) v.R2.BackgroundColor3 = a.BackgroundColor3 v.R3.BackgroundColor3 = a.BackgroundColor3 v.R4.BackgroundColor3 = a.BackgroundColor3 wait() end -- You can't do .Random like BrickColor... BrickColor has an index and it select random colors from that. The proper way to do 'random' with Color3 is to use math.random... But remember if you do in fact do that. Use 1 to 0 or #/255 because they do it by a 'percent' thing as to guess. I could give a cleaner example but yeah, good luck!
