Grave Heraldry
Grave Heraldry (#2A3498) is a true 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 (235°, 57%, 38%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin gravis, heavy — also the noun grave (burial pit). As a color modifier, grave implies a deep-and-formal seriousness where the hue carries weight beyond its lightness alone. Sits at the deep-and-solemn end of the grid, parallel to solemn and funereal in tone.
Old French heraudie, herald-craft — the medieval European armorial-bearings system, where the heraldic tincture purpure (one of the rare stains) is rendered as a deep blue-violet on shields-and-banners since the 13th century. Heraldry color refers to a 14th-century French armorial-roll purpure tincture: a saturated, slightly cool deep blue-violet with the matte finish of vermilion-and-azurite-mixed armorial pigment.
