Caltech's official color system is made up of four palettes: a primary color, a neutral palette, a deep palette, and a bright palette.

Primary Color

Caltech's primary color is Pantone MS 1585c Orange for coated and matte print jobs. Use PMS 151 for uncoated print jobs.

Neutral Colors

Caltech’s neutral color palette complements the Caltech orange and should be used for projects with a more traditional, serious tone.

Bright Colors

Caltech's bright color palette provides an opportunity to adjust the temper of a piece from subtle to bold. These colors should be used as accents to the primary, neutral, and deep colors, and carefully selected based on what is appropriate to the tone of the piece.
