The phosphor was patterned Hence the electrons from the guns only fell on 1 side of the patterning or the opposite. Working with cyan and magenta phosphors, a reasonable confined-colour graphic could possibly be acquired. He also demonstrated the same technique making use of monochrome signals to supply a 3D graphic (known as "stereoscopic" in the time). An indication on sixteen August 1944 was the first example of a sensible color television technique. Focus on the Telechrome continued, and programs have been made to introduce A 3-gun Variation for full shade.

The Geer tube was just like Baird's principle but employed small pyramids with the phosphors deposited on their own outdoors faces in place of Baird's 3D patterning on the flat surface. The Penetron utilized a few levels of phosphor along with each other and greater the strength of the beam to get to the upper layers when drawing those hues. The Chromatron made use of a list of focusing wires to choose the coloured phosphors organized in vertical stripes over the tube.
