This is a common question/complaint. However, short of experimenting with
your Windows Appearance, there is nothing you can do in Excel to change it.
It does seem to be related to the user's monitor

When you select a number of cells in Excel 2003, the cells are highlighted
in
a nice dark blue colour - easily identified even when selecting random
cells
using the ctrl key.

However in Excel 2007, this shading is a very pale blue colour and hard to
distinguish - can it be changed?
