/* Dr. Ax Ali - color tokens. V.2609.11.09, superseding 2026-09-01.
 *
 * EIGHT hue families, each paired: one value per ground. The anchor is one
 * of them - it is still the single accent, but it lives in the spectrum so
 * the whole set reads in one view.
 *
 * THE RULE: paper text lands at L* 27-47, ink text at 57-93, and between
 * them is a dead zone illegible on both. Inverted, every paper value takes
 * white and every ink value takes black; the --on tokens carry that type
 * color so a fill is never guessed at.
 *
 * TWO KNOWN COLLISIONS, both kept on purpose:
 *   anchor / red on ink   dE 0.029  - red's ink value was derived by lifting
 *     United Red and landed on the anchor, which was not a family then. The
 *     anchor cannot move and United Red carries an association worth
 *     keeping, so both stay. DO NOT SET THEM SIDE BY SIDE ON A DARK GROUND.
 *     On paper they are 0.121 apart and fine.
 *   gold / green on ink   dE 0.079  - IDEO Yellow against Tennis Green. Both
 *     are named associations and both are used as fills, so they rarely
 *     meet as letters.
 * For scale: teal was retired at dE 0.069 to blue.
 *
 * TWO FAMILIES ARE FILLS ON PAPER, NOT TYPE: gold and the anchor. IDEO
 * Yellow reads 1.14:1 as letters on paper and #EC622C reads 3.2:1. A yellow
 * that clears 4.5:1 on white sits at L* 48 and is a dark mustard - measured,
 * not assumed - so both trade text-safety on paper for staying themselves.
 * The anchor had a third value, a darkened #C54412, so it could be type on
 * paper; it was carrying 140 elements and was deleted this pass, because one
 * accent cannot be three values. The wordmark's period and the D in the EiD
 * lockup keep the anchor on paper - they are the mark (law 33), not type.
 *
 * TWO FAMILIES WERE RETIRED: jade (no association, sat beside teal) and
 * teal (dE 0.069 to Knicks Blue on ink, wedged between blue and green).
 * --ok followed them onto green, sharing with the "ready" fill on purpose:
 * both mean the work is good.
 *
 * WHERE THE COLORS COME FROM. Seven of the eight carry an association:
 *   red    Manchester United     green   a tennis ball
 *   orange the anchor            blue    the Knicks
 *   gold   IDEO                  violet  University of Washington
 *   pink   3rd Brain, Bo the Brain
 * Brown is named for what it is. UW Purple and Bo Pink arrived as given
 * values with their opposite half derived from them.
 *
 * Contrast is against #FBFBFE on paper and #111111 on ink. Every role of every
 * value is measured; nothing here is picked by eye. */
