colour words and parts of speech

[David Gil]

I'm seeking examples of languages in which different colour words belong 
to different parts of speech.

An example of such a language is Hebrew, in which most colour words are 
adjectives, but one, "txelet", denoting 'pale blue', exhibits the 
grammatical properties of a noun.

Does anybody know of any other such examples? 

Thanks,
