Prism was mainly inspired by two things, the sketches of Rudolf Koch for Prisma and the proportions of Avant Garde by Herb Lubalin. Even when the proportions and widths stay the same from ExtraLight to Black, you get the opportunity to change the weight and get a complete new look for that typeface by changing the grayscale or color. It is a modern combination for headlines, that want to have a different look.
Prism is available at myfonts.com.
