I can't duplicate your problem. I assume we're talking about creativex.net/forums.

When I look at the two dark themes, the search box is black and I cannot read the Google Custom Search in either dark theme but when I click on the search box it is a black background with white text. I can read it fine.

There's nothing in this mod that is changing font colors, you'll have to go into the Style Variables for each skin to mess with how that looks if you don't like white text on a black background for your search field.
