Color Usage Guidelines

At Caltech, we have a wide variety of design applications that fall inside our visual identity system. To maintain consistency, it's important to use the color(s) appropriate to the tone of the piece you are creating.

Use the diagram and color pairings below to help determine what colors are appropriate for your materials.

Please note: When printing with Pantone is not possible, please use the CMYK conversion. The RGB and HEX conversions are more suitable for use in digital materials; please see the Web Colors section for more information.

Color Pairings

The color pairings suggested below are grouped in order from formal to bold applications. The most formal looks stay in the range of the primary and secondary palette, while bolder looks combine the Caltech orange with impact colors. We recommend limiting your palette to three or four colors.
