I am using Crystal Reports 2011. 

I have a formula, @Classification,  that has four possible results:

First
Expanded
Reserve
Quarantine

I want the font color to change based on the result of that formula.  Since orange is not available as a conditional formatting color, I have set the font color of the field to orange and then applied conditional formatting.

If {@Classification} = 'First'
then crGreen
else
if {@Classification} = 'Expanded'
then crBlue
else
if {@Classification} = 'Reserve'
then crBlack

The problem I am encountering is that once I apply the conditional formatting, 'Quarantine' is no longer orange.  It changes back to black.  But the colors of the other classifications are correct.

How can I resolve this?

as an FYI you can use the color(r,g,b) to set any color value you want and not be limited
e.g.
if {@Classification} = 'Quarantine'
then color(255,165,0)
