[Plugin: PhotoContest Plugin] Fixing stylesheet(s) for dark themes

I installed the photocontest plugin into the sliding door theme and I’m having trouble fixing some of the instances of text so they will show up on the black background.

I have looked at the css files for both the theme and the plugin and I’m at a loss for how to get the firstCol, secondCol, and otherCol classes to appear white or a light color on the upload page.

I’m also having trouble fixing the “save” button on the upload page. The text is very nearly white on the light colored button.
