the explanation above shows the need for mau to distinguish from fruit in vietnamese why then is my answer" we see the orange coloured plates " wrong. It seems to me the same logic applies
Is "màu" required here? All of the examples I've seen so far of colors used as attributive adjectives have not had a classifier.
Yes. Sometime you can skip " màu" but in this case if you don't put " màu" . We will think it's fruit not color . Did you get it ? If you don't undersand ask me any question. ^^
