Unwavering Rhododendron

#b0409e
Notes

Unwavering Rhododendron (#B0409E) is a true magenta 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 (310°, 47%, 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Unwavering
adjective

Old English un- (negation) plus wafrian (to flicker). As a color modifier, unwavering implies a saturated-and-constant quality where the hue maintains its full strength without flicker or shift. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm in usage.

Rhododendron
noun

Eurasian and Himalayan Rhododendron genus — particularly the R. ponticum and R. arboreum species, whose deep-magenta truss-flowers cover the lower Himalayan and Caucasian highlands in May. Rhododendron color refers to a fully bloomed Rhododendron arboreum terminal truss in a Himalayan understory: a saturated, slightly cool deep magenta with the velvet finish of fresh broad-petaled bell-flowers in dense terminal clusters.

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.
