The Seattle Mariners’ visual identity, a crucial element in establishing the franchise’s brand since its inception in 1977, has undergone several significant transformations that reflect shifts in design trends and team eras. Each logo incarnation, spanning the original trident to the contemporary compass rose, utilizes distinct color palettes and typography, cementing a rich, evolving history for the Major League Baseball club.
The Nautical Evolution: A Deep Dive into the Seattle Mariners Logo History
1977 – 1980
The inaugural visual identity of the Seattle Mariners featured a large, bright yellow circle, bordered by a slender, dark blue ring. Inscribed within this primary logo were the words “Seattle Mariners” across the top, and just beneath it, “Baseball Club.” The most distinctive feature was the central wordmark, where the initial letter “M” in “Mariners” was ingeniously substituted by a navy blue trident, firmly establishing the franchise’s nautical theme.
1981 – 1986
The Seattle Mariners implemented a minor update to their branding, introducing a revised logo that centered the trident ‘M’. In this iteration, the new design prominently featured a five-pointed white star with a dark blue outline as the background element.
Layered on top, the central figure remained the distinctive, three-dimensional-effect blue letter “M” styled as a trident, which was now accented with a thin yellow outline to enhance its visibility and volume.
This change subtly modified the secondary mark, used primarily on caps and batting helmets, while maintaining the franchise’s established color scheme of royal blue and athletic gold.
1987 – 1992
The newly introduced team logo creatively featured the shorthand for the team name, “M’s.” These blue letters were prominently positioned at the core of a large white baseball, which was detailed with distinctive blue stitching.
1993 – Present

The Seattle Mariners logo, officially unveiled in 1993, represents a successful fusion of the sport of baseball with the maritime heritage suggested by the team’s name. Moving away from the earlier trident designs, the club’s developers introduced an emblem centered on a marine compass, a symbol deeply tied to navigation and the city’s coastal identity.
The core of the design is a stylized compass rose, a traditional nautical element. A small baseball is artfully positioned at the very center, seamlessly connecting the team’s professional sport with its regional theme. Radiating from this center point are directional rays pointing toward the cardinal directions. These rays employ a subtle two-tone effect (using both light and dark shades of Northwest Green and Navy Blue), giving them a distinct three-dimensional, beveled appearance that suggests dynamic movement.
Seattle Mariners Color Palette and Codes

The Seattle Mariners’ modern visual identity, established with the iconic Compass Rose logo in 1993, is defined by a distinct palette that visually roots the team in the Pacific Northwest. The primary colors are Navy Blue and Northwest Green, accented by Silver, White, and a touch of Red.
The Navy Blue (#002C56) provides a deep, traditional foundation, evoking the expansive ocean. The Northwest Green (#005C5C) is the franchise’s most unique color, strategically chosen to distinguish the team and connect directly to the geographical identity of Seattle. Silver (#C4CED4) provides a clean, modern contrast and emphasizes the sharp angles of the Compass Rose. White (#FFFFFF) ensures high contrast and legibility, while the subtle inclusion of Red (#D0011B) adds a dynamic, contrasting element to draw the eye to the logo’s core.
