Light sea green

Where it sits

Light Summer palette

Light sea green is an anchor color in Light Summer. Its closest relative outside the palette is Cool mint #9DC4B5, a True Summer color, at a perceptual distance of 6. That is near enough for that season to wear it as a neutral, with the accents kept in its own palette.

At RGB 143, 198, 180 the green leads, the blue is not far behind and the red is clearly lower. The blue sitting close to the green is what keeps it cool. The moderate spread between the three is what makes it soft rather than bright. It is the color of sea glass. Lighten it and it becomes Light Summer's cool mint; add grey and it becomes Soft Summer's greyed aqua.

A Light Summer wears it as a mid-tone: a knit, a shirt, a summer dress, a skirt. It gives the palette a green that has presence without weight. It works with soft white, dove grey and soft navy, and it sits well next to powder blue and cool soft rose.

Retail calls it sea glass, seafoam, jade mist, aqua haze and sage mint. Marine Layer's Latigo Bay has landed on it. Seafoam is the most reliable name. Sage is usually greyer and warmer, and belongs to the Soft seasons. It is mostly a spring and summer color in stores.

Easily confused with

The nearest color is True Summer's cool mint at six points, close enough to pass as the same. Light Summer's own cool mint is ten points off and paler. Light Spring's warm mint is twelve points away and has more yellow in it; her warm aqua is fourteen and brighter. Soft Summer's greyed aqua is thirteen points off and dustier. This is a color all three Summers can wear, with Light Spring able to borrow it at a pinch.

The nearest named colors in other seasons, by perceptual distance (ΔE in CIELAB; under 10 is hard to tell apart on a screen, over 25 is a different color).
