Design is tweaked from Matamp, but the style is all copied, the American ones are dirty, lots of distortion from crude construction. New Matamp come from Matamp and are well engineered amps so are much cleaner and influenced by what you put in. Matamp do colours if they have the stock, but their supplier wants bigger orders and they are a small run kinda company. You can order whatever you want from them, as long as they can get the stuff to cover it (or you supply it, cloth backed for their glue).
