Dense Tyre

#7d17a5
Notes

Dense Tyre (#7D17A5) is a true violet with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (283°, 76%, 37%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Dense
adjective

Latin dēnsus, thick / crowded — sharing root with English condense. As a color modifier, dense implies a saturated-and-tightly-packed quality where the hue carries maximum pigmentation per visual unit-of-area. Sits at the bold-and-saturated end of the grid, parallel to thick and concentrated in usage.

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.
