Handcrafted Cyclone

#040b3a
Notes

Handcrafted Cyclone (#040B3A) is a deep blue 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 (232°, 87%, 12%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Handcrafted
adjective

English compound hand + past-participle crafted. As a color modifier, handcrafted implies a neutral-and-hand-built-and-skilled quality, the neutral color of Mingei-Japanese and American-Craftsman-and-Arts-and-Crafts hand-built-and-quality-craft furniture-and-pottery surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to crafted and artisanal in usage.

Cyclone
noun

Greek kyklos, circle — the deep-cool-gray spiral-cloud structure of tropical Hurricane-and-Typhoon and extra-tropical mid-latitude cyclonic low-pressure systems. Cyclone color refers to a Hurricane Katrina-period satellite-image of the Gulf-of-Mexico cyclone-eyewall: a dark cool-gray with the optical complexity of cumulonimbus-spiral-band-and-eyewall against the warm Gulf-water sea-surface temperature.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
