Bold Tyre

#8538b9
Notes

Bold Tyre (#8538B9) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (276°, 54%, 47%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

Tyre
noun

Ancient Phoenician city on the Lebanese coast — the industrial-scale production site for Tyrian purple (the μύρεξ shellfish-dye that ruled Mediterranean elite color codes from 1500 BCE to 1453 CE). Tyre color refers to a Tyre-produced Tyrian purple dyed Roman toga picta: a saturated, slightly cool deep violet with the matte finish of multi-bath Bolinus brandaris shellfish dye on woolen toga cloth.

Display P3 representation

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.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
