If you're building a custom keyboard with Cherry Green switches and RGB backlighting and are looking for keycaps or switches that minimize light bleed, there are a few key options to consider.

South-Facing RGB Keycaps – These are ideal for minimizing light bleed while ensuring that your RGB lighting is vibrant and clear. South-facing keycaps are designed to fit Cherry MX switches like your Cherry Green, and they direct the light in a way that reduces light spillover.

PBT Double-shot Keycaps – PBT keycaps are highly recommended for their durability and resistance to wear. The double-shot design means the legends (key markings) are not prone to fading, and they also help reduce light bleeding compared to thinner ABS keycaps.

Translucent Keycaps – If you're aiming for brighter and more diffused RGB effects, translucent or semi-transparent keycaps may allow for better light diffusion, although they could increase light bleed depending on the quality of the material.

For the best options, you can explore a variety of keycaps and accessories specifically tailored for RGB backlit keyboards on ShopGalactica. They offer a selection of keycaps and switches designed to optimize your lighting effects and minimize issues like light bleed.
