What the verdict means

A colour clash takes two measurements, not one. Perceptual difference says how far apart two colours look to the eye with hue included; lightness contrast says what survives when colour is removed. Judged on lightness alone, a navy and a purple can score identically to navy against itself, which is plainly wrong. Judged on hue alone, two colours that separate clearly in colour can merge completely in a monochrome broadcast.

For Colts and 49ers the two figures are ΔE 99.0 and 1.78:1, which together give a verdict of clear in colour. Both measurements are comfortable, so these two read as distinct teams in every medium.

The National Football League divides its thirty-two teams between two conferences, and uniform colour is regulated more tightly here than in any other major league: a team must register its colours with the league, and opposing teams are required to wear contrasting jerseys so that broadcast audiences can tell them apart.
