[Closed]Why " 18:50:34.036 - Color cannot be assigned to"?

Here is the scripts

----Variables--------------------------
local p = script.Parent
print("Test")
print("Test.")
------------------functions--------------------------------------
function OnTouched(fall)	
local h = fall.Parent:FindFirstChild("Humanoid")---Need to rmb is hit
	if h ~= nil then
		p.BrickColor.Color = BrickColor.new(128,255,0)-- Color Codes from: http://www.rapidtables.com/web/color/RGB_Color.htm
		p.CanCollide = true
		wait(3)
		p.BrickColor.Color = BrickColor.new(225,0,0)
		p.CanCollide = false
		wait(3)
		p.BrickColor.Color = BrickColor.new(128,255,0)-- Color Codes from: http://www.rapidtables.com/web/color/RGB_Color.htm
		p.CanCollide = true
	end
end
script.Parent.Touched:connect(OnTouched)

Thanks!

You CANNOT assign a brickcolor from RGB (red, green, blue). So you go to brickcolor in properties and hover over a color u want the color to be. REMEMBER IT IS CASE SENSETIVE. Like this

script.Parent.BrickColor = BrickColor.new("Bright green") --i dont remember where to capitalize, so this might be wrong

Gui's have colors from RGB, though. But this is a brick. Not a gui
