User blog:Scp-1471/Wikia CSS Help

So recently I wanted to change the CSS on my wiki but I couldn't figure out how to get the color hex codes correctly. I would just like to know where to place the correct hex codes to get it to look like the original color scheme.
 * Background is an image


 * buttons: #FFFFFF
 * header: #000000
 * Main: #000000
 * Links: #64BAE8
