Reach for #17103b when a design needs a dark background with more character than black. This deep indigo sits very low in lightness with a dusty, muted finish, so it reads night-sky rather than electric purple. It works best as a dominant base in dark mode layouts and moody branding, where its low saturation keeps large areas calm instead of loud. White text holds strong contrast against it, passing WCAG AA for small body text. Pair it with warm accents like burgundy or muted gold to keep the palette from going cold.
