CSS parse errors from a generated stylesheet

I have a dynamic stylesheet which generates the following stylesheet.

body {
    background-color: #3a3a3a;
}
div#header_text {
    color: #3a3a3a;
}
div#footer_spacer {
    background-color: #3a3a3a;
}
table开发者_StackOverflow中文版#content_container {
    border-top: 6px solid #3a3a3a;
}
iframe#producten_container {
    border-left: 1px solid #3a3a3a;
}
div#footer_text {
    background-color: #646080;
}
#page_title {
    color: #646080;
}

This causes parse errors in the CSS validator. The following errors occur:

Value background-color Parse Error
Value Error : color Parse Error
Value Error : background-color Parse Error
Value Error : background-color Parse Error
Value Error : color Parse Error 

I think this CSS looks fine. Can anyone see what I'm doing wrong here??

the w3c validator lists those as warnings, just to indicate that you are duplicating the same colour in multiple places

you could consolidate some of the colours into a general class to avoid duplication, but as i mentioned the validator just issued warnings at these, not full on errors.
