98SE/Excel2000/Numeric Data

Hi all !
(A2-A1) goes in A3. All cells are numeric format.
If A3 is positive, this cell should show an unsigned number
with a font/color I choose. Maybe a custom color.
If A3 is negative, this cell should show an unsigned number
with a font/color I choose. Maybe a custom color.
In A3 I do not want leading zeros or decimals and no sign.
How to format cell A3 ?
Looked at Excel Help, and tried conditional formatting and
the [Red]#;[Green]#;[Green]# variations, but get colors I do
not want - what are Excel's color definition codes ?
Eg is there a [Darkgreen] - I do not think so.
Any help much appreciated ...
regards

 

Green doesn't have many variations and the darkest (green as opposed to sea green , bright green, etc.) isn't very dark. Lots more options with blue.

There is a color labeled Dark Green but my display at work (Intel 82845G) displays it as sort of a light black.

 

Thanks Newt, where do I find the color labels that Excel
recognises ?
regards

 

Found how to do this - thanks for help.
regards
PS Excel only knows 8 basic colors, but with the cell formatting
you can set a conditioned cell font to a color of choice.
