In implementations of a color picker, a color picker is generated and exposed in the context of color adjustment, making it easier for a user to select an appropriate color than with full-screen color pickers. A color picker acts as a window into a larger color map by exposing a portion of the color map selectable with touch gestures, enabling a user to easily access any content of a color map having very large numbers of color, at any desired level of detail, and determine a desired color. An indicator of current color at a fixed position of a color picker is updated in real time as content exposed by the color picker is updated. Hence, the current color is determined without obstruction by a user, as opposed to a user touching directly on a color to select a current color.
