The Commodore 64 in multicolour mode: 160 pixels across, each twice as wide as tall, sixteen colours that the VIC-II chip chose to look good on a composite TV rather than to be pure, and four-by-eight cells that each hold at most four of them. The light-blue border round the dark-blue screen is the machine's face.
A TV output and a few hundred bytes of colour memory. Doubling pixel width halved the memory a colourful screen needed, and the sixteen were picked to form nice gradients at nine luminance levels, which is why C64 art is browns, mauves and greys rather than primaries.
The figure is rasterised at 160 by 200 and blitted at a two-to-one pixel aspect. Each slot asks for two Lospec palette entries by light; then every four-by-eight cell is audited and any colour past its three commonest is remapped to the nearest one it kept. The boot text, READY. prompt and PETSCII frame are the three-by-five font in four-by-eight cells.
