How do I use BrickColor?

Hey guys! I had forgotten how to make a new part change color with script. This is what I got:

function RegenPart()
    newPart = Instance.new("Part", workspace)
    newPart. -- I need to know how to use it here.
    newPart.FormFacor = "Custom"
    newPart.Size = Vector3.new(2, 0.4, 1)
    newPart.Position = Vector3.new(39, 4.19, -8.5)
    newPart.Anchored = false

end

RegenPart()
