An improved color picture tube according to the invention includes an evacuated envelope enclosing a substantially rectangular cathodoluminescent screen, a color selection electrode suspended in register with the screen by a support structure, and an electron gun. The support structure includes a plurality of studs attached to the envelope adjacent to the corners of the screen. The support structure also includes a plurality of spring assemblies. Each spring assembly includes a first bimetal member attached to the color selection electrode and a second bimetal member having an aperture therein for engaging one of said studs. The first and second bimetal members provide longitudinal and rotational compensation, respectively, for maintaining the color selection electrode in register with the screen when the electrode and the spring assemblies are heated.
