I propose a feature that can change part of the coloration of all Normal-damage weapons and shields to the player's color. The feature is optional, and thus toggleable. Of particular interest are the Normal Tortodrone items, the Swiftstrike Buckler, the Iron Slug, the Defender series, and the Calibur series.
I'd also like the Grasping Aura, the Celestial cosmetics, summoned Mecha Knights/Turret Kits, and the Snarbolax set to have this option.
