<P> The Jets are currently the only team in the National Football League whose entire primary uniform, from helmet to socks, consists of only two colors (apart from the NFL shield and American flag decals). The Indianapolis Colts' blue - and - white uniforms have no third / trim color on their jerseys, pants or socks, but their helmets have gray facemasks . The Oakland Raiders' home jerseys and pants are black and silver only, but the uniform has white on the socks and helmet - logo decals, and the road jerseys are white with black numerals and silver trim . The Detroit Lions have an alternate / "throwback" uniform that is blue and silver only . </P> <P> The Jets began play in 1960 as the Titans of New York, whose uniforms were navy blue with old gold numerals, gold pants with two parallel blue stripes on each side, and navy blue helmets with a single gold stripe down the center and no logo decals . The white jerseys had navy blue numerals . The original Titans uniform designs resembled those of Notre Dame due to an affinity the franchise's original principal owner, Harry Wismer, had for the Fighting Irish . Wismer, who was considered a sportscasting pioneer, broadcast replays of Notre Dame football games prior to owning the Titans . In 1961 the Titans added UCLA - style shoulder stripes (white and gold on the blue jerseys, navy blue and gold on the white jerseys), changed the pants striping to a blue stripe flanked by white stripes, and employed a somewhat brighter shade of gold . </P> <P> When a Sonny Werblin - led syndicate purchased the team prior to the 1963 season and renamed it the Jets, the entire uniform was redesigned and replaced . Navy and gold were abandoned in favor of kelly green and white; white pants and green or white jerseys . Werblin had embraced those colors because he was born on Saint Patrick's Day . The jersey sleeves were opposite - colored (white on green and vice-versa) from shoulder to elbow, with thick stripes above and below the TV numerals . The pants were white with two parallel green stripes on each side, and the socks were green above the ankle with two parallel white stripes around the calf . The new helmets were white with a single green stripe down the center; the logo decal on each side was a silhouette of a jet airplane in green, with the nose pointed toward the front of the helmet and the word "JETS" in thick white sans - serif italics along the fuselage . In 1964, the single green stripe became two parallel stripes, and the jet - plane decals were replaced with a white football shape outlined in green, with the word "JETS" in green sans - serif italics in front of "NY" in green outline serif lettering, and a miniature football at bottom center . The decals were difficult to see from a distance (or on television), so the colors were reversed and the decals enlarged in 1965 . </P> <P> This design remained largely unchanged through 1977, apart from some variations to the numeral and lettering typefaces, the angle of the helmet decals, and adjustments to the shoulder and sleeve striping due to changes in NFL jersey tailoring and materials . The white stripes on the socks were eliminated in 1975 . Also, for at least one game in 1971 the Jets used a variation of their white jerseys that had no green stripes on the shoulders above the green sleeves . </P>
