Bright Colors

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.
