Invalid CSS

I have an error I can not seem to solve with my css style sheet. I get the following error:

"Same colors for color and background-color in two contexts #menu_child4 and .logo_m"
The thing is both classes have the same color and that is it. The background color is not specified, so I am not sure what the problem is. Unless it is because I have specified the color twice - so the error is because it is redundant data. Is there a way of specifying color only once for two different classes?
Would appreciate any help and advice that can be given. Cheers
