Examples of a user interface (UI) for depletion level selection are described herein. In some examples, a control element is displayed in a UI to select a color depletion level for a color printing substance of a printing device. A predicted cost-per-page to print is displayed in the UI based on based on a selected color depletion level. A color map for the printing device is determined based on the selected color depletion level and a separate black depletion level.
