As a keyboard enthusiast, I believe that everyone is familiar with the green PCB colors, and the inspiration of this set is from the colors of PCB. The golden sublegends(triple-shot) in the base kit is from the metal pads on the PCB.
The colors of these keycaps will be matched to the actual PCB colors.
Golden Sublegends
In order to better match the concept, there is triple-shot base kit for making the sublegend’s gold, so that the sublegends can change their color with different lighting conditions.
