   When designers state contrast ratios for sRGB hex values, do they take the nonlinear nature of sRGB values into account? Because if they don't, those contrast ratios don't work as expected. Actually, it's even worse, because you have to know the contrast ratio of the display in order to find the real contrast ratio, and that's only representative if you're viewing the display in a pitch black room where it doesn't reflect any light.

      It's much easier to state a contrast ratio for print media. All you have to do is find the ratio between the reflectivity of your darkest colour and the reflectivity of your lightest colour. Granted, this will depend on the type of ink (and the type of paper, if tinted or unbleached), but those are parameters you can control. It's so much harder to get meaningful values when you're not in control of the picture reproduction, as is the case for an electronic display.
