It's practically impossible to go by what other people are seeing, too, because of personal monitor settings. Some people like more brightness and contrast while others prefer to turn down those settings and the results for everyone are different.
I sometimes use a disclaimer in my auction listings on eBay: "Actual colors may vary from image viewed on each individual's monitor due to personal monitor preference settings. We do not guarantee colors for this reason." By using this I can avoid issues if a customer is not happy with the color and I'm certain to describe the color as best I can in the description.
I do see a lipstick red, though!
