Phosphoric Orbit Eucalyptus

#43d29e
Notes

Phosphoric Orbit Eucalyptus (#43D29E) is a true teal 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 (158°, 61%, 54%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Phosphoric
adjective

Greek phōsphóros, light-bringer — adjectival suffix -ic. As a color modifier, phosphoric implies a saturated-and-cool-glow quality, the bright color of match-tip-strike and firefly phosphorus-emission luminescence. Sits at the bright-and-cool end of the grid, parallel to phosphorescent and fluorescent in usage.

Orbit
modifier

Latin orbita, track-or-wheel-rut. As a color modifier, orbit implies a Keplerian-ellipse-and-circling quality, the visual register of Keplerian-ellipse-and-Newton-Principia-orbit hand-Keplerian-ellipse-and-circling Keplerian-ellipse-and-Newton-Principia-and-Tycho-orbit orbit-and-Keplerian-ellipse-and-circling surfaces under Keplerian-ellipse-and-Newton-Principia-and-Tycho-orbit Royal-Society-and-celestial-mechanics 17th-century-observation-light. Sits at the modifier-and-cosmic end of the grid, parallel to axis and parsec in usage.

Eucalyptus
noun

The genus Eucalyptus, the gum trees that dominate the Australian forest canopy and have been planted across the world for fast-growth timber and the menthol-camphor oil. The color refers to mature eucalyptus leaves with their pale waxy bloom: a soft, slightly muted blue-green with the matte finish of cuticle that reflects more light than typical foliage. Cooler than sage, warmer than mint.
