Resounding Khram

#375fb7
Notes

Resounding Khram (#375FB7) is a true azure 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 (221°, 54%, 47%) 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

Resounding
adjective

Latin resonāre, to echo back — present-participle of resound. As a color modifier, resounding implies a saturated-and-echoing-and-imposing quality where the hue reverberates visually like a cathedral-bell ring. Sits at the bold-and-resonant end of the grid, parallel to resonant and booming 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.
