Solid Pluto Rose

#c42344
Notes

Solid Pluto Rose (#C42344) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (348°, 70%, 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Solid
adjective

Latin solidus, firm, dense — used as a color modifier since the seventeenth century for hues that read as continuous and unbroken: a solid blue is one with no variation across the surface. Implies high saturation combined with optical density. Sits in the bold-bucket alongside strong and robust, slightly more focused on uniformity.

Pluto
modifier

Latin Pluto, Roman-god-of-underworld-and-dwarf-planet. As a color modifier, pluto implies a Roman-god-of-underworld-and-Kuiper-belt-dwarf-planet quality, the visual register of Roman-Pluto-and-New-Horizons-flyby hand-Roman-god-of-underworld-and-Kuiper-belt-dwarf-planet Roman-Pluto-and-New-Horizons-flyby-and-Tombaugh-Regio pluto-and-Roman-god-of-underworld surfaces under Roman-Pluto-and-New-Horizons-flyby-and-Tombaugh-Regio 2015-flyby-and-heart-shaped-Tombaugh-Regio dwarf-planet-light. Sits at the modifier-and-zodiac end of the grid, parallel to neptune and saturn in usage.

Rose
noun

The Latin rosa, the Greek rhodon, the Persian gul — every European language has a different name for the same flower and the same color. Rose covers the spectrum from blush to fuchsia depending on the cultivar, but in pigment shorthand it means a cool, slightly bluish red — the inside of a damask petal, the dye that washes out of madder root.
