Wholesome Chàm

#6488d3
Notes

Wholesome Chàm (#6488D3) 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 (221°, 56%, 61%) 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

Wholesome
adjective

An adjectival form of whole — used as a color modifier since the sixteenth century for hues that read as healthy and unadulterated. Wholesome cream, wholesome wheat: moderate saturation combined with the optical impression of a natural origin. Sits at the crisp-bucket alongside genuine.

Chàm
noun

The Vietnamese word for indigo — and vải chàm, the indigo-dyed cotton worn by H'mong, Tay, and Black Thai ethnic groups in Northern Vietnam. The color refers to a freshly chàm-dyed H'mong skirt: a saturated, slightly cool deep blue with the matte finish of multi-bath plant-dyed cotton.
