The invention discloses a color acquisition method and apparatus. The method comprises the steps of when a target color background image is displayed by using a target display control in a WPF (Windows Presentation Foundation), obtaining first current coordinates of a current moving point in the target color background image; obtaining a color at the first current coordinates when the target color background image is displayed by using the target display control; and storing the color and determining the color to be a selected color of the current moving point. Through the technical scheme provided by the invention, when the target color background image is displayed by using the target display control in the WPF, the first current coordinates of the current moving point in the target color background image can be automatically obtained, and the color at the first current coordinates is stored and serves as the selected color of the current moving point, so that the color in a moving position of the current moving point can automatically serve as the color selected by a user, and a color selection function of a palette can be conveniently realized in the WPF.
