Unfortunately I don't yet have a good answer, so this +// approach may yet change. Current approach: +// - Hardcode colors so that we can be sure we use legible combinations of +// foreground and background. +// - Use only the terminal palette in the range 16-255. +// - Not all terminals may support more than 256 colors.
