Smoky Toadflax
Smoky Toadflax (#282389) is a deep blue 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 (243°, 59%, 34%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
An adjectival form of smoke, used as a color word since at least the fourteenth century. Smoky implies a slightly muted, slightly hazed quality — as if the color were seen through a layer of suspended particulate. Used across both deep and neutral buckets: a smoky black has slightly less density than pure black; a smoky gray has slightly less coolness than pure gray.
Eurasian Linaria vulgaris and L. purpurea — snapdragon cousins with hooded violet-and-yellow flowers naturalized across temperate roadsides and waste-ground. Toadflax color refers to a fully bloomed Linaria purpurea spike: a saturated, slightly cool deep blue-violet with the matte finish of dense small two-lipped snapdragon-form flowers. The Old English name refers to the linear flax-like foliage of the wild Linaria genus.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
