The Sinclair ZX Spectrum of 1982: 256 by 192 pixels, one bit each, with colour kept separately for every eight-by-eight cell, an ink and a paper from one brightness half. Six thousand nine hundred and twelve bytes for the whole screen, which is what a cheap home computer could afford.
Because colour lived on a coarser grid than the drawing, a figure that crossed a cell recoloured the whole cell. Artists learned to draw in two-colour blocks and to tolerate the halo of wrong-coloured rectangles around anything that moved. The clash is the signature, not a bug to hide.
A one-bit bitmap of the figure, dark where its tone falls under a Bayer threshold. Each attribute cell takes the paper colour most of its figure pixels ask for, and an empty cell next to a coloured one inherits it, which is the clash. The cells holding the glasses carry the FLASH bit, so they swap at 1.6 hertz. The border shows the loading stripes.
