Stark Khram

#283a8a
Notes

Stark Khram (#283A8A) is a true blue with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (229°, 55%, 35%) 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

Stark
adjective

Old English stearc, stiff / strong — sharing root with German stark and Dutch sterk. As a color modifier, stark implies a deep-and-uncompromising contrast where the hue stands without modulation against its substrate. Sits at the deep-and-formal end of the grid, parallel to severe with sharper visual register.

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.

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.
