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()
