Patterned Stratus

#b5d5ec
Notes

Patterned Stratus (#B5D5EC) 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 (205°, 59%, 82%) places it in the balanced 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.

Etymology

Patterned
adjective

Old French patron, pattern / model — past-participle of pattern. As a color modifier, patterned implies a pale-and-repeating-design-and-structured quality, the pale color of William-Morris-and-Liberty-of-London hand-block-printed-and-repeated decorative-and-structured pattern-design surface. Sits at the pale-and-soft end of the grid, parallel to marbled and figured in usage.

Stratus
noun

The Latin meteorological term for layer cloud — the low, gray-blue overcast clouds that cover the entire sky in mid-latitude winters. Stratus refers to a fully developed stratus deck on a North Sea winter morning: a soft, slightly muted deep blue-gray with the optical density of homogeneous low cloud.
