Cyberzorn: Light Yellow Highlighted Text
Mike Zornek found a subtle little issue on some web sites, where they use a very subtle style of highlighting that doesn't stand out enough. Either you want to emphasise text, then really do put emphasis on it, or you don't, then leave it be. Anything else just leads to clutter. The light yellow in this case is too soft to stand out noticeably, and thus only hampers readability. Though my guess is that this also depends on your screen's gamma: If it's light (like it's typically on Macs) the colour will be much more subtle than if you have a dark gamma. So, remember to preview your site on different computers and OSs.
