Cool Hyacinth
Cool Hyacinth (#CB9ED7) is a soft violet 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 (287°, 42%, 73%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary green. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English cōl, of low temperature — used as a color modifier as the complement to warm. Cool gray, cool blue: the optical impression of a slight blue-green shift, even within otherwise warm or neutral hues. Sits across the crisp, hushed, pale, and neutral buckets.
Hyacinthus orientalis, the bulb cultivated in Persian and Ottoman gardens since at least the eleventh century, named in Greek myth for the youth Hyakinthos accidentally killed by Apollo. The color refers to a fresh purple-blue hyacinth in spring bloom: a saturated, slightly violet-shifted blue with the matte finish of densely packed corollas. Cooler than larkspur, warmer than iris, with the perfumed weight of a flower whose scent fills a greenhouse from doorway to back wall.
