I do! Much less eye strain and easier to read for me. In fact, I read your comment in white text on a black background. My eyes are very sensitive to light in general though.

I hope you know that black color light doesn’t mean less light.

* "black color light" does not exist. Light cannot be black.

* Each pixel in an LCD has 3 subpixels (red, green, blue). There is a light source behind the pixels. To display black, white, or anything in between (gray), all 3 subpixels allow an equal amount of light through. What controls the shade is the amount of light allowed through each. For black, the lowest possible amount of light is allowed through.

* On an OLED display, like the one in my phone, each pixel emits its own light and can be controlled independently. A black pixel on an OLED display emits practically 0 light and even uses less power as a result. This is why blacks look way better on OLED displays.

* See for yourself. Use your phone in a dark room and fill the screen with white only and then try again with black.

* You know how black absorbs light and white reflects light? Black does not absorb light because it is black. It's black because it absorbs light.

That's not how light from a screen works
