Voluptuous Tiller Sapphire
Voluptuous Tiller Sapphire (#134EB4) 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 (218°, 81%, 39%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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
Latin voluptuōsus, pleasurable — derived from voluptās (pleasure). As a color modifier, voluptuous implies a saturated-and-rich-and-curving-sensual quality, the deep-rich color of Rubens-and-Boucher baroque-and-rococo flesh-and-fabric tonality. Sits at the bold-and-saturated end of the grid, parallel to lush and plush in tone.
Old French telier, steering-bar. As a color modifier, tiller implies a steering-bar-attached-to-rudder quality, the visual register of small-boat-and-skiff-tiller hand-carved steering-bar-attached-to-rudder polished-and-varnished tiller-and-helm small-boat-architecture surfaces under polished-and-varnished tiller-and-helm small-boat light. Sits at the modifier-and-nautical end of the grid, parallel to helm and bow in usage.
An iron-and-titanium-bearing corundum — the same mineral as ruby, hardness 9 on the Mohs scale, mined for two millennia from Sri Lanka, Burma, Madagascar, and the Cashmere mines of British India. The color refers to a fine Kashmir-cut sapphire: a saturated, slightly violet-shifted deep blue with the gem's signature internal velvet — a quality of light scattering in the stone that faceted glass cannot replicate. Cooler than cobalt, deeper than azure.
