Color Variants are a unique modifier on weapons that can randomly appear on weapons obtained from defeating enemies in battle. A Color Variant weapon will have a different color than its original variant, and can be identified by the unique rainbow icon on the bottom left of the weapon icon (). Color Variant weapons can also be identified with its unique "Color" indicator on the Item Details menu. Certain Photon Art effects generated from Color Variant weapons will also have unique colors compared to a regular weapon.
Variant colors are currently fixed on each weapon and cannot be changed or transferred to other weapons. Using a Color Variant weapon as the base for a multi-weapon will however transfer the color effects to the other weapon.
