ZX82 ABCDEFG: a bicolor drolatique font generator
[dpla's ZX Spectrum edition – version 1.0 or ROIAOAIO]

294 visible text characters, in 'Extended ASCII' (U0020-FF) and a few beyond.
7 code pages (CP) to switch from, and 48 cells left unassigned (in CP 4 to 6).
Feel free to add your private glyphs, provided you retain the original mapping;
you may replace them with invisible formatting controls (e.g. for animations).
The CP switches are 7 visible control characters, applied once or indefinitely,
that is: K/B/R/M/G/C/Y → temporary; KY/BY/RY/MY/GY/CY/YY → permanent.
Please, bear in mind that my main mapping (CP 0) is based on our 6 vowels,
contrary to A-Z substitutions (like David B. Kelley's "6-Color Binary Alphabet").
This implementation uses 7 colors in ascending RGB on a white background
(hence my title: a 8-bit allusion to the ZX Spectrum Ink and Paper on screen).
Example: "Hello·world!" = "BY K RM RK MM MM GK •CR GK GM MM BM KK"
where the letters = their abbreviated color (0-6), and 'Space' / "•" = White (7).
Typically on a display, you can resort to a pair of characters (any block / bar)
but you can use the material of your choice (e.g. balloons, the air being "W"),
even derivate in color (symbols), size (micro), view (vector, 3D), language…
