why is game.Workspace.part.BrickColor = Really Red not working?

Hello, tttvbb!

The reason why it didn't work was because you didn't assign brickcolor to the colour your trying to perceive. Make sure you use BrickColor.new()

BrickColor takes an argument, which is the colour.

Here's the code you were trying to perform

game.Workspace.Part.BrickColor = BrickColor.new("Really red")

if you want to get the rgb (red,green,blue) values use this

game.Workspace.Baseplate.Color = Color3.fromRGB(255, 0, 0)
