I have been following up with Customer Support about the lack of color in the UI since Lion. Ultimately, they called this a "feature". I would suggest that making the UI harder to use by removing all color is not a feature. While Heathers icons above work for the list on the left side of evernotes, there is no way, as far as I can figure, to add color to the icons along the top. Yes, the icons are in the resource file, but changing them has no effect on the UI. Since there are no appearance features for Evernotes, I would hope that they make available to option to tweek the interface to fit individual needs.
