Using Seattle Mariners Colors

Web & CSS

Use the HEX or rgb() values directly in CSS. The primary color, Navy (#0C2C56), works well for headers and calls to action — check the contrast readouts above to choose white or black text for accessible pairings.

Print

For print, convert to the CMYK values listed in the table. When color accuracy matters — vinyl, fabric, or signage — match against a Pantone (PMS) chip from the team's brand guide, since screen color rarely matches ink exactly.

Merch & apparel

Thread and heat-transfer vinyl are specified in Pantone, so bring the CMYK and hex values to your supplier as a starting point. Remember that team names, logos, and marks are trademarks — the color values are a reference, not a license.
