Reference notes
#00022E is a very deep, saturated blue color closest to Black. The color has RGB channels of 0, 2, and 46; in HSL terms, it is centered near 237 degrees with 100% saturation and 9% lightness. In a design system, this cool reading is a useful shortcut for deciding whether the color should act as a primary accent, a supporting surface, or a quiet divider. The safest usage pattern is to test it against both light and dark surfaces, then reserve the weaker text pairing for decoration rather than essential labels. If the color feels too forceful at full strength, the lighter, darker, and desaturated variants usually provide a calmer path for production UI. For editorial or product interfaces, reserve the most saturated use for accents and repeat softer variants in borders, labels, or background fills. This makes it useful for interfaces that need weight, contrast, or a more formal visual register. In CSS systems, define it as a custom property first so variations, shadows, and gradients can stay consistent.
