Re: Color Contrast Testing Visual Question

The tester's comments do not appear to make sense. Apart from monochrome monitors, it is almost impossible to buy a monitor that doesn't support 24-bit colour, so the displayed colours will always correspond accurately to the hex codes that have been specified.

It is possible that they are referring to the screen resolution rather than the colour depth, in which case they may have just written up the issue badly. Perhaps there are different colour combinations at different screen widths, depending on how the responsive design has been implemented.

Subject: [WebAIM] Color Contrast Testing Visual Question

Hi,
This is a question for my understanding as a totally blind person. A tester reports that content passes or fails contrast testing depending on monitor settings. We are using Colour Contrast Analyzer. If this is the case, how can we depend on accurate results, because we would not know the kind of monitor an audience has?

Thanks.

Jim
