Seattle Mariners Color Codes
The Seattle Mariners colors are commonly used across team branding, uniforms, digital graphics, fan designs, presentations and web projects. The team’s official MLB website confirms the club identity, division placement and T-Mobile Park information, but a public Mariners page with official Pantone, CMYK, RGB and HEX specifications was not found during verification. For that reason, the values below should be treated as best available estimates unless marked otherwise by an official team or MLB brand guide.
| Color Name | Pantone | HEX | RGB | CMYK |
|---|---|---|---|---|
| Navy Blue | Best available estimate: PMS 289 C | #0C2C56 | 12, 44, 86 | 100, 60, 0, 56 |
| Northwest Green | Best available estimate: PMS 7721 C | #005C5C | 0, 92, 92 | 100, 0, 47, 47 |
| Metallic Silver | Best available estimate: PMS 877 C | #C4CED4 | 196, 206, 212 | 5, 0, 0, 20 |
| Red Accent | Best available estimate: PMS 199 C | #D50032 | 213, 0, 50 | 0, 100, 65, 0 |
Important Accuracy Note
The Seattle Mariners do not appear to publish a public official color specification page with verified HEX, RGB, CMYK and Pantone values. The team information in this article is based on official MLB and Seattle Mariners sources. The color code table uses best available estimates from established team color references and should not be treated as an official Mariners brand guide. If you are producing commercial merchandise, licensed artwork or official brand materials, confirm requirements directly with the Seattle Mariners, MLB or the appropriate licensing authority.

Design Tips for Seattle Mariners Color Combinations
For a clean Mariners-inspired design, use navy blue as the dominant background or heading color, Northwest green as the main accent and metallic silver as a neutral support color. Red should usually be used sparingly because it functions better as a small accent than as a primary Mariners design color.
Suggested Digital Pairings
- Navy Blue and Northwest Green: Best for bold headers, sports graphics and strong team-themed layouts.
- Navy Blue and Metallic Silver: Best for clean website sections, tables, infographics and presentation slides.
- Northwest Green and Metallic Silver: Best for secondary graphics, badges, icons and social media accents.
- Red Accent with Navy Blue: Best for small details, callouts or logo-inspired highlights.
Accessibility and Contrast Tips
When using Seattle Mariners colors on websites or apps, make sure text has enough contrast against the background. Navy blue generally works well with white or very light text. Northwest green can also work with white text in many layouts, but contrast should still be checked before publishing. Metallic silver is better for borders, backgrounds and secondary design elements rather than small body text.
