Cooler Master CK351 Optical Keyboard Review

Lighting

The CK351 has good lighting with the only colours that are a bit middling being the usual two of a yellow/orange colour which tends to be either slightly green on the yellow side, and too yellow or red depending upon which end of the orange scale. The other is the old standby that is a part of nearly every RGB lighting setup we’ve come across where the white leans slightly towards the blue end of the spectrum. In both cases these photos make the problem look worse than it is to the naked eye, where the colours at the top of this page are more representative of what you can expect.
