Rosewill Unveils Color Keycaps for Cherry MX-based Keyboards
 

To help organize and color-code your keyset, in case the simple F and J indices don't cut it for you, Rosewill unveiled Color Keycaps. Sold in 104-piece sets, in four colors - yellow, red, green, blue, and pink; the key-caps are compatible with all mechanical keyboards that use Cherry MX switches. Rosewill showed off an example of a heavily color-coded keyboard. Interestingly, these key-caps don't appear to support back-lit illumination.
