ABSTRACT A means is disclosed for selectively increasing the emission of the several color guns of a color picture tube by placing a variable resistance between the control grid and the screen grid corresponding to each said color gun. This privides a source for increasing the voltage on the control grid of that color gun. As the voltage on the control grid is increased, the emission of that color gun is increased, thereby making it possible to blend the colors of the several color guns.
