Installation is literally a snap: remove your keycap, snap a Color Modifier onto the switch, and replace the keycap. As the plastic alters the color of your original LED instead of replacing it, the Color Changers work best with white LEDs, but if you know exactly the shade and composition you’re going for, the sky’s the limit. We are including 135 Color Modifiers in this pack, giving you enough materials to differentiate colors between sections of your keyboard or simply keep some spares around for experimentation or back-up.
