Depending on the screen the difference between the used yellow and white is hard to distinguish. For example on a Dell Inspiron notebook screen there is no visible difference while on some othere screens the difference is perfectly visible.

Perhaps a different color or at least a slightly darker yellow could be used?

I'll take a look at this for the next upgrade.

I concur with helium. It's definitely hard to pick out on my current screen.

I tip my (Dell Mini) laptop backwards a bit to check the color.

Side note, it's sad that the whole cross-computer color thing still hasn't been worked out (at least in the practical world, even if technologies officially exist). I also went crazy over color a few years ago when I got a Mac. That took too much research and trouble ...
