What colors go with dark sea green

Each match keeps dark sea green's saturation and lightness and rotates only the hue, so the relationship is the wheel's and nothing else. Any of these can be an accent beside dark sea green as the primary; the harmony guides explain which rule suits which interface.

Complementary

The opposite hue, 180° away — the strongest contrast, best kept to one accent per screen.

#bc8fbc

Split-complementary

The two neighbors of the complement, at 150° and 210° — most of the contrast with less tension, and two accents instead of one.

#a68fbc

#bc8fa6

Triadic

Two hues at 120° and 240° — three evenly spaced signals, the scheme charts and category colors want.

#8f8fbc

#bc8f8f · rosybrown

Analogous

The neighbors at −30° and +30° — calm and cohesive, with emphasis coming from weight and size rather than hue.

#a6bc8f

#8fbca6

A UI color palette built from dark sea green

The eight semantic roles an interface actually uses, derived from dark sea green as the primary with the split-complementary rule: secondary and accent rotate around the wheel, and the five neutrals take the hue at lightness steps tuned for light and dark mode. This is the same derivation the palette generator runs — open it there to change the rule, drag the anchors, or export the set as CSS variables.

Using dark sea green in an interface

Green means success and 'on' — reserve one green for that job before you use another as a brand color. Sea green, forest green and teal are calm enough to lead a palette; the neon greens are for dark-mode accents and little else. Whichever role dark sea green takes, define it once as a token rather than repeating the keyword: the semantic palette guide covers the eight roles, and the guides to complementary, triadic and the other color schemes explain how to weight the matches above.
