Lacy Sundown

#c5ccef
Notes

Lacy Sundown (#C5CCEF) 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°, 57%, 85%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lacy
adjective

Old French laz, lace — adjectival suffix -y. As a color modifier, lacy implies a pale-and-decorative-and-open-network quality, the pale color of Edwardian-period hand-tatted-and-bobbin-lace bridal-and-formal-wear delicate-network-pattern textile. Sits at the pale-and-decorative end of the grid, parallel to filigree and cobwebby in usage.

Sundown
noun

English compound for the moment of sunset's last upper-limb contact with the horizon — the brief window when the eastern anti-solar sky is at its deepest Belt of Venus indigo before nightfall. Sundown color refers to a clear-sky eastern anti-solar horizon at sundown: a saturated, slightly cool deep blue-violet with the optical complexity of Rayleigh-scattered Belt of Venus light against the rising Earth shadow.
