Caltech's official color system is made up of three palettes: a primary color, a neutral palette, which includes complementary shades of gray and white, and a bright palette, which complements the primary and neutral colors, providing opportunities to express greater energy and boldness.
Caltech's primary color is Pantone 1585 Orange for coated and matte print jobs. Use Pantone 151 for uncoated print jobs.
Caltech's neutral color palette is a complement to the Caltech orange and should be used to provide visual depth and sophistication to communications materials.
Caltech's bright color palette provides an opportunity to adjust the temper of a piece from subtle to bold. These accent colors should be used as complements to the primary and neutral colors, and carefully selected based on what is appropriate to the tone of the piece. See the color usage guidelines for more direction on selecting colors for your materials.
