Cadet Blue

Cadet Blue is a desaturated blue-green, named after the dark teal of British naval cadet uniforms. The CSS hex is dustier than the historical dye, sitting in muted-teal territory. It is one of the rare CSS colors that ages well in modern flat-design palettes because its low chroma keeps it from looking dated. As a secondary surface color it suits marine or heritage brands, or works as a calming background for content-heavy pages where stronger blues would distract. Cream or warm white handles type contrast. Body text against white passes AA at headline sizes; smaller sizes need careful verification.
