GigaScreen
Two specially prepared images are displayed on the screen rapidly after each other. The palette is increased to approximately 102 colors due to the color-mixing effects of the rapid flipping between images.
For Pentagon machines, a hardware modification is available which directly combines the two alternate screen areas into the video signal, thus eliminating the flicker associated with this method. Furthermore, the gigascreen and hicolour techniques may be employed together to produce even richer-coloured images; this format has been named DithVIDE and BZither, both names referring to the dithering methods employed when converting true-colour images to the format.
