Homemade Submarine

#280509
Notes

Homemade Submarine (#280509) is a deep red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (353°, 78%, 9%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Homemade
adjective

English compound home + past-participle made — sharing root with make. As a color modifier, homemade implies a neutral-and-handcrafted-and-domestic quality, the neutral color of American-and-English-cottage hand-made-and-home-craft household-textile-and-pottery surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to handmade and handcrafted in usage.

Submarine
noun

The military-naval underwater vessel — and the dark gray paint applied to the surface portions of submarine hulls to minimize visual signature against the gray of an ocean horizon. The color refers to a NATO submarine's exposed sail: a soft, slightly muted dark blue-gray with the matte finish of marine anti-corrosion enamel. Cooler than gunmetal, warmer than midnight.
