Ok, I get the thing about specifying color and background-color
together.  So I specify:

background-color: transparent;

in my CSS file.  And I still get the warning.

The CSS file is:  http://ed.mullen.home.comcast.net/styles/ahs.css

The warning is:

Line : 41 (Level : 1) You have no background-color with your color : #logo_1

If I specify a color (e.g. #fff;) the warning goes away.  So, is
transparent an illegal value?  Doesn't seem to be according to:

http://www.w3.org/TR/REC-CSS2/colors.html
http://www.w3schools.com/css/pr_background-color.asp

Color me confused.

Ed,

Transparent is valid, but does not resolve the validator's concern that
the user may have assigned a background color which is incompatible with
your new foreground color.

It's a warning, not an error.  If transparent is appropriate to your
situation, leave it.

Thanks, Chris, for the explanation.
