The user device detects content color data describing the color of content that is overlaid by a UI element on a display of a user device, the UI element including one or more components and a UI element background. The user device determines component color data describing the color of the one or more components of the UI element, and dynamically determines transparency data for the UI element background using the content color data and the component color data. The user device displays the UI element in accordance with the transparency data and the component color data.
