There was a spirited discussion today about the effect of bright light glare on application color themes. A lot of discussion about solorization and saturations and such. My point in the discussion was that all of that is irrelevant because the main factor is not the sun on the colors. It's the color's impact on the glass screens reflection of the light. Dark themes turn screens into mirrors. Ever noticed that you can see your face reflecting back at you in a dark screen but not a light one? Well the same happens with the sun.

Here is my unscientific experiment. Same screen with Intellij put into a dark and light screen and angled such that a light is reflecting back at the camera:
