Stalwart Damask

#155ab2
Notes

Stalwart Damask (#155AB2) is a true azure with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (214°, 79%, 39%) places it in the highly saturated band at a mid 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Stalwart
adjective

Old English stǣl-wyrðe, stable-and-worthy. As a color modifier, stalwart implies a saturated-and-loyal-and-firm quality where the hue carries the dependable-and-trustworthy visual presence of a Knight-Templar guard. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm in usage.

Damask
noun

A reversible patterned fabric originally woven in Damascus — used in Renaissance European bed-hangings, Ottoman ceremonial robes, and traditional Italian Lucchese silk. Damask blue refers to a deep-blue silk damask: a saturated, slightly cool deep blue with the satin finish of patterned woven silk.
