I get why kids ask this. I don't get why adults ask this. If you have normal color vision and don't have a tumor in your visual cortex your red is as close to my red as the red subpixels are on two units of the same television. Sure, you can't look at them and positively measure their identicalness, but they're being generated with the same hardware.
