The official Seattle Mariners colors are navy blue, Northwest green and silver. The primary color is navy blue (#0C2C56), paired with Northwest green (#005C5C) and silver (#C4CED4). Red (#D50032) works as a small accent. This palette arrived with the 1993 rebrand and still runs across the logo, uniforms and merchandise.
Seattle Mariners Color Codes
| Color | Swatch | HEX | RGB | CMYK | Pantone |
|---|---|---|---|---|---|
| Navy Blue | #0C2C56 | 12, 44, 86 | 100, 60, 0, 56 | PMS 289 C | |
| Northwest Green | #005C5C | 0, 92, 92 | 100, 0, 47, 47 | PMS 7721 C | |
| Silver | #C4CED4 | 196, 206, 212 | 5, 0, 0, 20 | PMS 877 C (metallic) | |
| Red (accent) | #D50032 | 213, 0, 50 | 0, 100, 65, 0 | PMS 199 C |
A quick honesty note. PMS 877 is a metallic ink, so it will never print the same way #C4CED4 renders on screen. If you are doing a one-color job, most shops swap in a cool gray. And the Pantone values you see floating around for the green sometimes get listed as 7716 instead of 7721. Treat the 7721 figure as the widely used match, not gospel handed down from the club’s brand book.
Every Color in the Mariners Palette
Navy Blue (#0C2C56)
This is the anchor. It fills the circular field behind the compass rose in the primary logo, it is the cap crown, and since 2023 it is also the base of the road jersey (more on that below). It reads almost black under stadium lights, which is exactly why it works next to green.
Worth knowing: this is a deep, slightly muted navy blue rather than a true dark blue. Sitting at 19% lightness, it has more presence than the flat #000080 web navy people default to.
Northwest Green (#005C5C)
The one everybody argues about. Half of Seattle calls it teal, the club calls it Northwest green, and technically both camps have a point. At a hue of exactly 180 degrees it sits right on the line between blue and green, which is the textbook definition of teal. The Mariners named it after the region, not the crayon.
It shows up in the compass rose outline, the trident marks, the alternate top, and every Friday home game at T-Mobile Park. It is deep enough to read as a proper dark green from the upper deck, which was probably the point.
Silver (#C4CED4)
The trim color. Outlines, piping, jersey number borders. It has a faint blue cast (hue 210), so it is closer to a cool blue gray than to true silver metal. On merch it often gets printed as a metallic foil, which is a different animal entirely.
Red (#D50032)
Small, but it exists. The red lives in the compass rose needle inside the primary logo. That is basically it. Plenty of color-code sites skip it, and honestly you can build a Mariners layout without ever touching it.
Mariners Uniform Colors
Home: white with navy lettering and Northwest green trim. Sunday home games get the cream throwback with royal blue and gold.
Road: here is the wrinkle. Seattle dropped the gray road jersey after 2022 when MLB and Nike capped teams at four jerseys plus one City Connect. The road look now is a navy top with gray lettering over gray pants with navy piping.
Alternate: the Northwest green top, mandatory for Friday home games and also used in spring training. And the 2023 City Connect, which ignores the modern palette completely: royal blue jersey, black pants, yellow and gold accents (Nike named the shades Rush Blue, Sundown and Amarillo), with a black-visor cap. It nods to the 1969 Seattle Pilots and the 1940s Steelheads.
Color History and the 1993 Rebrand
The Mariners launched in 1977 wearing royal blue (#1D428A) and gold (#FFC72C). That original scheme lasted through 1992 and gave us the upside-down trident logo, which owner George Argyros scrapped in 1987 partly over a superstition that an inverted trident insults Poseidon. Baseball people are like that.
The full color change came in 1993. Out went royal blue and gold, in came navy, Northwest green and silver, plus the compass rose logo. That palette has held for more than three decades now, which in MLB terms is unusually stable.
The cream Sunday alternate reintroduced royal blue and gold as a throwback, so the old scheme never fully disappeared. Then 2023’s City Connect leaned even harder into it, adding black to Seattle baseball for the first time on an official cap.
Using the Mariners Colors in Design
Digital work: use the HEX or RGB values. Print: use CMYK, or Pantone if your job supports spot colors. Never eyedropper a JPEG of a jersey and call it accurate.
Copy-ready CSS:
:root {
--mariners-navy: #0C2C56;
--mariners-northwest-green: #005C5C;
--mariners-silver: #C4CED4;
--mariners-red: #D50032;
--mariners-white: #FFFFFF;
}One practical warning. Navy on Northwest green fails WCAG contrast badly (the ratio lands around 1.5:1). They look great side by side in a logo, terrible as text on background. Put white or silver between them and you are fine.
