A color selection apparatus for a cathode ray tube. A mask is formed having a long axis and a short axis. A frame supports the mask in one of a long axis direction and a short axis direction. The mask has a plurality of strips separated by a predetermined distance. A plurality of first beam apertures are formed as single long slits between the strips in a center portion of the mask. A plurality of second beam apertures are formed on outer portions of the mask to both sides of the center portion of the mask. The second beam apertures are divided into a plurality of individual units within a single column by real bridges and at least one dummy bridge for each individual second beam aperture unit. The at least on dummy bridge extends inwardly from the strips but does not cross completely through the individual second beam aperture unit.
