All Might's Hero Suit

How this color came to be

All Might — civilian name Toshinori Yagi — is the Number One hero in My Hero Academia, the long-running shonen series that began as a Kohei Horikoshi manga in 2014 and as a Bones-animated anime in 2016. His most iconic hero costume is the "Silver Age" suit, an open homage to American superhero design from the Superman and Captain America era. The dominant color across the torso, sleeves, and core paneling is a deep navy — pulled down in brightness rather than amped up in saturation, and nothing like the bright primary blues most Japanese hero designs reach for.

The hex breaks down to HSB(230°, 73%, 47%). Hue 230° sits a touch on the cyan side of pure blue (which lives at 240°) — close enough that the difference is subtle on its own, but enough to soften the navy from feeling clinical. Saturation is high at 73%, but brightness is the critical dimension — only 47%, under half. That's what makes the navy read as "deep" and "serious" instead of as a children's-cartoon primary blue. Pull either dimension wrong and the color stops looking like All Might and starts looking like a generic superhero blue.

Players miss this color almost every time on the brightness slider. The instinct when matching a navy is to stay around 60–65% brightness; All Might lives lower. The other trap is hue — a true cobalt would sit at a different hue and higher saturation. To match: drop brightness to about 47%, hold saturation in the low 70s, and keep the hue near 230°. Stepping fully up to 240° pushes the navy toward a flat primary blue and loses the small cyan softness that gives the suit its weight.
