Abstract: Various embodiments pertain to techniques that determine a perceived mood or personality that corresponds to a user and present a web page responsive to the determination. In some embodiments, the perceived mood or personality corresponding to a user can be determined according to a user's interaction with various colors presented on a web page. For example, responsive to a user hovering over a particular color presented on a web page, a perceived user characteristic, such as a perceived personality or mood corresponding to the user can be ascertained. A web page can be presented according to the perceived personality or mood. In various examples, style sheets can be used to present the web page in a way that corresponds to the perceived personality or mood corresponding to the user.
