Certain Galah

#b52e8a
Notes

Certain Galah (#B52E8A) is a true magenta 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 (319°, 59%, 45%) 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

Certain
adjective

Latin certus, fixed / sure — sharing root with English concern and certify. As a color modifier, certain implies a saturated-and-unambiguous quality where the hue declares its character without hesitation. Sits at the bold-and-confident end of the grid, parallel to assured and decisive in usage.

Galah
noun

Australian Eolophus roseicapilla — a Cacatuidae parrot of the Australian arid zone, whose breeding-plumage adults have a brilliant deep-magenta breast against pale-grey wings. Galah color refers to a Eolophus roseicapilla breast feather field in raking light: a saturated, slightly cool deep magenta with the velvet finish of carotenoid-pigmented feather barbs against the gray melanin-substrate wing-feather background.

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.
