1. A method of correcting a desired color of a pixel to be displayed in an optical see-through display through which a background is visible, the method comprising: identifying a display profile of prescribed colors arranged to be rendered by said display; identifying a background color of said background associated with the respective pixel; determining a perceived profile of predicted colors which are predicted to be perceived by a user by adding said background color of the background to the prescribed colors of the display profile; identifying a selected one of the predicted colors which most closely matches the desired color by comparing the desired color to the predicted colors of the perceived profile; and instructing the display to display the prescribed color which is associated with said selected one of the predicted colors such that an observer substantially perceives the desired color.
