Reference notes

#BFF128 is a balanced, saturated green color closest to Green Yellow. The color has RGB channels of 191, 241, and 40; in HSL terms, it is centered near 75 degrees with 88% saturation and 55% lightness. In a design system, this balanced 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 badges, highlights, product accents, and moments where quick recognition matters. In CSS systems, define it as a custom property first so variations, shadows, and gradients can stay consistent.
