In 2007 I am having difficulty distinguishing highlighted areas

[Bear Black]

When using Excel 2007 I have a very hard time distinguishing areas and/or
cells that I drag over.

Is there a way to darken the highlight?

I have the same problem being an "old" vision impaired person! This is also
a common complaint about Excel 2007.

Not much you can do about it. I've seen some folks recommend trying to
adjust your monitor brightness/contrast settings.

I have that problem too. On my laptop it is easier to tilt the monitor. Then
it suddenly become much more visible. But this is an unnatural angle for
looking at your monitor.
