Most of us cope just fine, so long as the contrast between the states is clearly different. My colour blindness is anomalous trichromacy, with a perception difference for red-green. Because the examples shared are a bright blue for on and black for off, I can see it just fine, however, I'd suggest making the switches off state back ground the same as the main background in this case. Aesthetically, it looks better.
