Resolute Kashmir

#4078d3
Notes

Resolute Kashmir (#4078D3) 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 (217°, 63%, 54%) 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

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Kashmir
noun

The northwestern Indian-Pakistani Himalayan region — and the saturated deep blue of Kashmir sapphires (the world's most prized sapphire variety, mined in the Padar valley). Kashmir color refers to a faceted Kashmir sapphire: a saturated, slightly violet-shifted deep blue with the gem's signature internal velvet.
