The word(s) "red" appears 489 time(s) in 438 verse(s) in Quran in Muhammad Pickthal translation.

(321) And no burdened soul can bear another's burden, and if one heavy laden crieth for (help with) his load, naught of it will be lifted even though he (unto whom he crieth) be of kin. Thou warnest only those who fear their Lord in secret, and have established worship. He who groweth (in goodness), groweth only for himself, (he cannot by his merit redeem others). Unto Allah is the journeying.

(322) Hast thou not seen that Allah causeth water to fall from the sky, and We produce therewith fruit of divers hues; and among the hills are streaks white and red, of divers hues, and (others) raven-black;

(323) And We have set a bar before them and a bar behind them, and (thus) have covered them so that they see not.

(324) They answered: Our Lord knoweth that we are indeed sent unto you,

(325) With what (munificence) my Lord hath pardoned me and made me of the honoured ones!

(326) Fruits. And they will be honoured

(327) They said: Build for him a building and fling him in the red-hotfire.

(328) Then, when they had both surrendered (to Allah), and he had flung him down upon his face,

(329) And We sent him to a hundred thousand (folk) or more

(330) (And again of their falsehood): He hath preferred daughters to sons.
