The question for asking colors is constructed similar to the way it´s done in English:

    Eng: What color is XXX?

    Tr: XXX ne renk? (Here, ne is what and renk is color)

The answer is also simple:

    Eng: XXX is red.

    Tr: XXX kırmızı.

However, note the difference in word ordering when you want to add a color (or any adjective) to an indefinite noun.

    Eng: A red XXX.

    Tr: Kırmızı bir XXX. (Not ´Bir kırmızı XXX´)
