What colors go with dark green

Each match keeps dark 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 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.

#640064

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.

#320064

#640032

Triadic

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

#000064

#640000

Analogous

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

#326400

#006432

Tints and shades of dark green

Tints add lightness toward white; shades remove it toward black. The hue and saturation stay fixed, so every step still reads as dark green — these are the hover, pressed, disabled and surface variants a single brand color needs.

A UI color palette built from dark green

The eight semantic roles an interface actually uses, derived from dark 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 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 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.
