«تَرَدَّى ثِيَابَ الْمَوْتِ حُمْرًا فَمَا أَتَى لَهَا اللَّيْلُ إِلَّا وَهِيَ مِنْ سُنْدُسٍ خُضْرٍ»
“He donned the red garments of death; night came and they seemed garments of green silk.”
This poetic illustration sets red against green within a developing image. Color is used to express more than visual appearance; it helps convey the contrast in the scene.
The effect called tadbīj depends on the poetic significance of the colors, not merely on naming two colors.
