As a keyboard enthusiast, I believe that everyone is familiar with the green PCB colours, and the inspiration of this set is from the colours of PCB.The golden sublegends in the base kit is from the metal pads on the PCB. In order to better match the concept and lower the cost at the same time, I choose tripleshot subs for making the sublegend’s gold, so that the sublegends can change their colour with different lighting conditions, rather than only a bland yellow colour.
