Hi,

We create Excel files with conditional formatting on Windows XP pcs. The
colors depend on the value of the cell: typical formatting i.e. red = bad,
green = good and variations in between.

But recently a mac user came back to us and the colours on his screen were
completely different. Not what I have been finding online related to Gamma
value (darker - lighter), but truely different.
For example: light pink on his screen was yellow. This was not the case for
the legend, a rectangle drawing with the same colour fill. That was slightly
lighter but still pink.

Does anyone have any ideas how we could fix this? Or how to test/reproduce
this when you don't have a mac?

Any help would be greatly appreciated!!
Kr,
