Punchy Port Heliotrope
Punchy Port Heliotrope (#5365F9) is a true blue with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (233°, 93%, 65%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
A modern adjectival form of punch, to strike sharply. Used as a color word since the early twentieth century for hues that read as highly contrasting and visually loud. Punchy red, punchy yellow: the implication is full saturation combined with optical impact. Sits across the bold and bright buckets, near vivid and striking.
Latin portus, harbor. As a color modifier, port implies a maritime-trading-city quality, the visual register of Lisbon-and-Marseille Mediterranean-Atlantic trading-port hand-built mediterranean-and-atlantic harbor surfaces under Iberian-and-Mediterranean afternoon harbor-city light. Sits at the modifier-and-place end of the grid, parallel to quay and dock in usage.
The genus Heliotropium — the cherry pie plant, named in Greek for its supposed habit of tracking the sun (heliotropism). The color refers to a fresh garden heliotrope cluster in late summer: a saturated, slightly red-shifted deep purple-blue with the matte finish of densely packed forget-me-not-style flowers. Cooler than mauve, warmer than indigo, with the perfumed weight of a flower whose vanilla-cherry scent fills a greenhouse.
Closest matches

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.
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.
