14 Degrees of Visibility

Brinton charts 14 degrees of visibility all the way from black type on a yellow background (the most legible) to blue type on red (the most offensive). This research is certainly nothing new today, but gets you thinking about how the theories have been exercised. Take, for example, the classic hazard symbols, or street signs—they each use the most visible color combinations per Brinton’s chart.
