Replete Sagittarius Crimson

#a7231c
Notes

Replete Sagittarius Crimson (#A7231C) 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 (3°, 71%, 38%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Crimson

Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.
