$*color_footer_background already exists. It's the orange color.

I don't know if the link colors should be changed because I don't know how much contrast is needed. The current colors which are used are yellow for text and white for links. The yellow color is the same which is used for the links of the navigation menu. Nobody remarked on this being hard to read so... The only possible issue I can think of is that the footer uses the reversed scheme: yellow for text, white for links as I said. Having yellow for links in the top menu and for text in the footer menu may be confusing. Or not.
