In my opinion, we do not appreciate colour until we see its importance in the animal kindgom. If it was not for 'Colour Language' many animals would be extinct.أَلَمْ تَرَ أَنَّ اللَّهَ أَنْزَلَ مِنَ السَّمَاءِ مَاءً فَأَخْرَجْنَا بِهِ ثَمَرَاتٍ مُخْتَلِفًا أَلْوَانُهَا وَمِنَ الْجِبَالِ جُدَدٌ بِيضٌ وَحُمْرٌ مُخْتَلِفٌ أَلْوَانُهَا وَغَرَابِيبُ سُودٌ (27) وَمِنَ النَّاسِ وَالدَّوَابِّ وَالْأَنْعَامِ مُخْتَلِفٌ أَلْوَانُهُ كَذَلِكَ إِنَّمَا يَخْشَى اللَّهَ مِنْ عِبَادِهِ الْعُلَمَاءُ إِنَّ اللَّهَ عَزِيزٌ غَفُورٌ
27. See you not that God sends down water (rain) from the sky, and We produce therewith fruits of varying colours, and among the mountains are streaks white and red, of varying colours and (others) very black.
28. And of men and Ad-Dawâb (moving living creatures, beasts, etc.), and cattle, in like manner of various colours. It is only those who have knowledge among His slaves that fear God. Verily, God is All-Mighty, Oft-Forgiving. [Holy Quran, 35:27, 28]
A mother bird is able to recognise whether her chicks need food or not from the colour of their gapes. And for many organisms the colours that exist on formations such as skin, scales and fur play an important role in the continuity of life due to their characteristics of absorbing or diffusing heat.
The language of colours is truly fascinating and clearly the backbone of most beautiful things. Even if one is not able to see colours, they can be told of its significance as one of the many blessings of Allah (SWT) upon all living beings.تُسَبِّحُ لَهُ السَّمَوَاتُ السَّبْعُ وَالْأَرْضُ وَمَنْ فِيهِنَّ وَإِنْ مِنْ شَيْءٍ إِلَّا يُسَبِّحُ بِحَمْدِهِ وَلَكِنْ لَا تَفْقَهُونَ تَسْبِيحَهُمْ إِنَّهُ كَانَ حَلِيمًا غَفُورًاThe seven heavens and the earth and all that is therein, glorify Him and there is not a thing but glorifies His Praise. But you understand not their glorification. Truly, He is Ever Forbearing, Oft-Forgiving. [Holy Quran, 17:44]
