Substantial Alkanet

#b22636
Notes

Substantial Alkanet (#B22636) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (353°, 65%, 42%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Substantial
adjective

Latin substantia, substance — adjectival suffix -al, derived from sub-stāre (to stand under). As a color modifier, substantial implies a saturated-and-weighty-and-material quality where the hue carries visual mass and presence. Sits at the bold-and-weighty end of the grid, parallel to weighty and hefty in usage.

Alkanet
noun

Anchusa tinctoria, the Mediterranean borage whose roots yield a red dye used since classical times for cosmetics and wine coloring. The color refers to fresh alkanet-dyed wool: a saturated, slightly cool deep red with the matte finish of plant-and-mordant dye. Cooler than madder, deeper than crimson.

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.
