The sky of the Grey Ruins always maintains the same color, or rather, in this foggy world, all living beings forget the definition of color. Even Lynch's Eye of Insight cannot penetrate the formidable power of this plane. All objects are reduced to mere outlines, devoid of other visual features.
Only when a new devil army arrives at this Nether River dock does a hint of crimson appear, like the only flickering candlelight in a thick fog. Even though it will soon vanish, that red's final flickering moment feels as long as a lifetime to Lynch.
So whenever the devil's army arrives, he rushes to the harbor to warm his eyes with the fleeting sight—even if it's merely the color of evil.
