how do I Check what color a block is?

basically im making a red light green light type game and I want the part to kill you when it is red but I dont know how to check the parts brick color, I want it to be like if part is this color then but I dont know how to check if it is that color.

Try checking the brick color as in your setting a brick color in code

if part.BrickColor == BrickColor.new('Black') then
	print('its black!')
end

I think you should use this simple method to know if it is red or green.

 if part.BrickColor == BrickColor.new('Lime green') then
    print('Its green!')
end

Try this

local part = game.Workspace:FindFirstChild("Part")

if part then
	print(part.BrickColor)
end
