#21212B Hex Color
Dusty indigo with an ashy finish
Not black and far from vivid purple, #21212b is a dusty indigo with a heavy gray cast. That low saturation makes it a strong dominant base for dark mode interfaces and moody brand palettes. Pair it with muted gold or dusty rose to draw out the violet undertone, since cool grays flatten it into plain charcoal. As a hex code, it stays versatile: white text on it reaches about 15.9:1 contrast, well past the 4.5:1 WCAG AA minimum.
