A method and system of increasing the intensity of secondary colors in sequential color display systems. The method utilizes light during a transition period between two primary color periods to form a secondary color. The light generated during this transition is generally not used since it does not represent a pure primary color, but instead typically starts as light of a first pure primary and ends as light of a second pure primary. A display controller determines which secondary color is needed, and the amount of the secondary color needed, and enables the transition or spoke light to contribute to the image during a time period appropriate to desired secondary color intensity given the intensity and switching characteristics of the light during the transition period. For example, light (210) filtered by a color wheel (200) during the transitional period (212 to 214) between a red (102) and green (106) filter is used to increase the yellow component of the image. Several optional methods are used to minimize the artifacts created by the spoke light and to adapt the secondary color boost to white-boosting spoke light recapture methods. In general, the spoke periods are used to boost the white level of de-saturated images and to boost the secondary colors of saturated images.
