Clearbra shows up more on darker colors. Chip repairing has little-to-nothing to do with dark or light colors. FAR MORE CRITICAL is metallic vs. non-metallic paint. Non-metallic paints are much easier to touch-up. Because metallic paints refract light differently depending on the angle of refraction, it's virtually impossible to touch in a chip and not have it look darker or lighter, depending on how the light is hitting the metallic particles with respect to the surrounding perfectly uniform paint. Your touch-up will not lay flat, due to miniscus effect. So it will reflect differenly, and always look a different shade in most lights. You can sand it flat and polish it, but you'll still always detect the transition.
