Excel 2003 Conditional Format Color Cells Issue in SharePoint 3.0
 

I have a Excel 2003 spreadsheed with conditional formatting: a cell changes
from red, to green, to yellow, depending on the value entered into the cell
-- it works fine. When the spreadsheet uploads into SharePoint 3.0 (published
with spreedsheet functionality), the colored cells all change to a light red
color. What must I do to keep the color assignments in the Excel spreadsheet
so they appear the same when viewed in SharePoint?
