Color scheme RPOL
Every year this happens, every year I tell people User Preferences>"Edit (or remove) your custom theme", use the dropdown at the bottom of the page to get the color scheme they want with the "grab them" button, then click "Create!" and you will be blissfully unaware (other than people going on about it for any holiday whose scheme they don't like) of any color scheme changes. Interestingly enough, the dropdown says the only unique ones are on April Fools and Christmas, but I'm sure they just use the regular color schemes for the others.
