Chroma

Chroma is a customization system added to Destiny in Update 2.2.0. It allows Guardians to add glowing colored highlights to certain weapons and armor pieces. Chroma comes in four colors- red, blue, yellow, or white.

Use
Chroma-compatible gear has two additional bubbles on its details screen. The upper bubble is used to activate the item's chroma effects, and has a certain color assigned to it. A chroma consumable of the same color must be spent to activate the effect.

The lower bubble is used to reroll the item's chroma color. Using this bubble will cost 100 glimmer and change the item's chroma to one of the four colors, chosen at random. If a chroma consumable has already been spent to activate the previous color, it will not be returned and is lost; the slot becomes inactive and a new chroma consumable must be spent to re-enable the new effects.
