Just like LCRY, but instead of glowing it turns to its deco color. Here is a better explanation:
When turned off, it appears as a dark, unsaturated blue color, no matter what deco color it is. When activated, its color changes to its deco color.

 LCRY shows its deco color even when it's deactivated. DCRY doesn't show its deco color when deactivated. Also, DCRY doesn't glow likr LCRY does.
