In the 1930s, the United States government created the Federal Housing Administration, which in turn created a series of maps which were using a color-coding system to determine which neighborhoods should and should not receive federal housing loans. Their residential security map was its own kind of color palette, and in fact was more influential than all of those color palettes that I had been studying in college combined.

Su mapa de seguridad residencial era su propio tipo de paleta de colores y, de hecho, era más influyente que todas las paletas combinadas que estudié en la universidad.
