Deep Periwinkle Thread

#a1aff3
Notes

Deep Periwinkle Thread (#A1AFF3) is a soft blue with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (230°, 77%, 79%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.
