tu as les yeux de quelle couleur means 'what colour are your eyes?' in French.
One singular eye is called un oeil but the plural is les yeux. Your eyes would be, using the polite, Tu form, would be Tes Yeux, or the more formal vous form would be Votres Yeux
Tu as les yeux noirs. Do not confuse with " tu as le regard noir" (you have a black look) which means you look angry
"tu me manques de plus en plus tous les jours / "tu me manques de plus en plus chaque jour"
T'ai les yeux beau. Literal translation is ' you have the eyes blue', but the adjective and noun are supposed to be in that order and 'the' is just how the say it. BUT if you said this to a french person it'd be weird because it's supposed to be pronounced with an accent.

Tu as des yeux magnifiques
Tu as (or "vous avez" politely) de beaux yeux. A famous quote of Jean Gabin to Michèle Morgan in the movie "Quai des Brumes" T'as d'beaux yeux, tu sais.
