Incell range W15:W31, percent values are font/background-color conditional
formatted.

In cell W10 is the following formula: =SUM(X15:X31)

What would the formula be to exclude in the sum, a cell having a green
background and a zero percent value?

First, there's not worksheet formula that looks at the colors used in the cells.

You could write your own UserDefinedFunction that looks at colors. Finding the
colors that are applied via Format|cells is straightforward. But finding colors
based on the conditional formatting rules is not for the weak at heart.

Chip Pearson has some code for the format|cells stuff at:
http://www.cpearson.com/excel/colors.htm
look for: Summing The Values Of Cells With A Specific Color

and he has some hellacious code for just finding the conditional formatting
stuff at:

=====
But if the value is 0, no matter what the color, it shouldn't affect the =sum()
formula.

0 + prettymuchanything = prettymuchanything.
