So, I meet a friend of mine who says: "michael, I met a woman who has
the most beautiful eyes I've ever seen".

And me, wanting to ask "seriously ? what color are they ?", I don't
have a way to ask because "klingons don't have a word for color".

Or I can say something like "how are they dyed/stained/tinted" ?

But the jay' problem is, that I'm not asking if she wears make-up..
