It's also important to consider the opposite perspective, when you're working on design touches that usually should be subtle. Some very common examples are lighting effects like gradients, drop shadows and cut-outs. These effects need to have quite a gentle contrast between the darker and the lighter colours, and if you start throwing around 25%+ differences in grey level your results could become overpowering for viewers with decent screens. Of course, in such cases, you also won't completely break your design for viewers with poorly configured screens or imperfect vision if the contrast isn't as strong to them, so you can afford to be more subtle than when choosing, say, foreground/background colours for body text.
