    THE PALETTE IS THE VGA SIXTEEN, NAMED BY INDEX, and the brightness rule is the one The
    Vortex's art runs on: 15 is the thing itself (a key, a value), 7 is text and every
    symbol that separates, 8 is brackets, frames and murmur. Hue is spent on the logo and
    on one meaning — 14 yellow is "not open yet". Nothing else is coloured for variety.   */
