Selhamawy,
There are some pseudo-workarounds available to you for this.
If you're distributing the reports over the web, you could use a formula like:
//@F1 -- just put a zero in.
0
using the condition,
if @F1 = 1 then crWhateverYourColourIs else NoColor
Pass the 1 to the formula from the web page, but not when printing.
