Color television is now possible with all-electronic equipment that does not make black-and-white receivers obsolete. in a recent demonstration the Radio Corporation of America used a new television camera to broadcast still pictures in full natural colors. When the electronic equipment is used a light beam is focused through the picture and then separated into component colors. Rapid-fire electrons then scan three colors - red, blue and green - and transmit 30 pictures a second for ach of the color images. At the receiving set the three images are projected on a screen to reproduce a single full-color picture. Today's black-and-white sets will receive transmission from future color stations by the addition of a converter, but the pictures will not be in color. Company officials say that years may pass before electronic color television is perfected for widespread use.
