Flashing Chartreuse Beam

#c9ff8f

Notes

Flashing Chartreuse Beam (#C9FF8F) is a soft lime with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (89°, 100%, 78%) places it in the highly saturated band at a light lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary indigo. For something softer, pull in its analogous neighbors on either side of the wheel.
