Abstract: A tinting material may be generated and applied to the backdrop of an application presented on a user interface. The user interface is presented on a display and includes a background. The background comprises a first color, which includes a luminosity value, a hue value, and a saturation value. A tint color, having a luminosity value, a hue value, a saturation value, and an opacity value, is received. The luminosity value of the first color is modified to generate a second color, and the hue value and saturation value of the generated second color are modified to generate a third color. A tinting material color is generated that includes the modified luminosity value of the second color, the modified hue value of the third color, and the modified saturation value of the third color, and an application is presented on the user interface that includes the tinting material color.

Abstract: Different aspects of a visual experience (e.g., a particular graphic and a particular color) may be separately selected, and then combined to create a theme. The theme may be applied to content, in order to provide a visual experience that is customized to a user's specifications. For example, a user may have an account with a web site. The web site may provide the user with controls that allow the user to select, separately, graphics and color (or some other aspects of the visual experience). The theme may be created based on the particular combination selected by the user. The created theme may be stored, or otherwise associated with, the user's account, so that the theme may be applied to content when the user visits a web site. Themes based on a combination of user selections may be applied to web content or any other type of content.
