How do I convert a Color3 Value to a RGB Value?

So, let's say I would want to get the Red value from a Part. I would use this code:

print(game.Workspace.TestPart.Color.r)

And it would output a number like "0.1234321" or something like that.... But how would I make it so that it prints out a RGB value from 0 - 255 instead of a Color3 Value 0 - 1?
