Does anyone know a jquery or javascript method or methods for testing hcm; whether it's black or white? I have an image on my site that shows up under normal circumstances, and an image that shows up under black, but need to detect if HCM is set to white.

  • there are CSS color names that reflect system color settings. these are the ones like buttonface, buttontext, threedshadow, tooltip, etc. these might not fully work on all OS/Browser combos, so test your targets. you can set the named color and then read the current color value to get an RGB for each one. – dandavis Jul 24 '13 at 18:35
