Saturated Thor Rose

#b40935
Notes

Saturated Thor Rose (#B40935) is a true red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (345°, 90%, 37%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Saturated
adjective

From the Latin saturatus, past participle of saturare, to fill. A technical color term in modern usage — saturation is one of the three axes of HSL (with hue and lightness). As a modifier, saturated implies that the hue is at or near its maximum chromatic intensity. Sits at the bold-and-bright top of the grid.

Thor
modifier

Old Norse Þórr, god-of-thunder-and-Mjölnir. As a color modifier, thor implies a hammer-Mjölnir-and-thunderbolt-and-red-bearded quality, the visual register of Norse-Thor-and-Mjölnir-hammer hand-hammer-Mjölnir-and-thunderbolt-and-red-bearded Norse-Thor-and-Mjölnir-hammer-and-Asgard thor-and-hammer-Mjölnir-and-thunderbolt surfaces under Norse-Thor-and-Mjölnir-hammer-and-Asgard Bilskirnir-and-Thrudheim-and-thunder-cart thunder-storm-light. Sits at the modifier-and-myth end of the grid, parallel to odin and loki 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.
