Chalky Powder Slate

#eceff3

Notes

Chalky Powder Slate (#ECEFF3) is a soft azure with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (214°, 23%, 94%) places it in the muted band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.
