I worked for a company with a large website. The designers were elite and worked in a darkroom on expensive Apple equipment. At some point, it turned out that users couldn't see a certain color on the website because it could be seen on an Apple monitor, but not on a mass-market laptop's TFT screen.
I have difficulty reading the light gray text on white/bright background that too many sites favor these days. I have a pretty good 4K 32 inch monitor. Even with a full Adobe color space capable and calibrated device in a darkroom I don't want to read that combination.
I don't get it, I have medically tested 120% color vision (it was a lengthy test), definitely nothing wrong on my side, so I don't understand at all what the designers and coders are seeing that they think that that is a great idea. The difference between the pixels is objectively bad, one can take a screenshot and look at the background versus text pixels.
