Stalwart Khram

#2541ab
Notes

Stalwart Khram (#2541AB) is a true blue 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 (227°, 64%, 41%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

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.

Khram
noun

The Thai word for indigo — used in the natural indigo dyeing of Phrae province textiles and the mor hom (indigo work-shirt) of northern Thailand's farming tradition. The color refers to a freshly khram-dyed mor hom: a saturated, slightly cool deep blue with the matte finish of Thai-style indigo cotton.
