Towering Forgetmenot

#0d3f3d
Notes

Towering Forgetmenot (#0D3F3D) is a deep cyan 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 (178°, 66%, 15%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Towering
adjective

Old French tour, tower via Latin turris — present-participle of tower. As a color modifier, towering implies a deep-and-vertical-and-architectural quality, the dark cool-gray of Salisbury-Cathedral-and-Chartres-Cathedral spire-and-tower against the sky. Sits at the deep-and-architectural end of the grid, parallel to imposing and looming.

Forgetmenot
noun

Myosotis sylvatica, the European forget-me-not — a small woodland-and-streamside wildflower whose pale blue five-petaled flowers symbolize remembrance and faithful love in European folk tradition. The color refers to a fresh forget-me-not flower: a soft, slightly cool pale blue with the matte finish of small five-petaled flower with yellow center.
