An-Nahl - 16:13

وَمَا ذَرَأَ لَكُمْ فِي الأَرْضِ مُخْتَلِفًا أَلْوَانُهُ إِنَّ فِي ذَلِكَ لآيَةً لِّقَوْمٍ يَذَّكَّرُونَ
[16:13]
And what He has created in the earth of varied hues most surely there is a sign in this for a people who are mindful.
And the things on this earth which He has multiplied in varying colours (and qualities): verily in this is a sign for men who celebrate the praises of Allah (in gratitude).
And whatsoever He hath created for you in the earth of divers hues, lo! therein is indeed a portent for people who take heed.
