Smooth Bluestem

#c4f2e4
Notes

Smooth Bluestem (#C4F2E4) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (162°, 64%, 86%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smooth
adjective

Old English smōþ, level, polished — used as a color modifier since the seventeenth century for hues that read as continuous without texture or break. Smooth tan, smooth gray: moderate saturation combined with optical evenness. Sits in the crisp-bucket alongside even.

Bluestem
noun

The genera Andropogon and Schizachyrium — North American native prairie grasses whose stems shift from green to blue-purple in autumn. The color refers to S. scoparium (little bluestem) in midsummer: a soft, slightly cool blue-green-gray with the matte finish of upright prairie grass.
