Colors that match green are blue, yellow, red, black, white and brown. It is important to consider the shade of green when attempting to match a color with it.
Analogous colors are ones that appear next to each other on the color wheel, and any color always matches well with its analogous colors due to their harmony. Green's analogous colors are blue and yellow, so green looks great when paired with either color.
Complementary colors lay opposite each other on the color wheel and also match nicely. The contrast between the two colors creates intensity. Green's complementary color is red, so the two look great together. Black, white and brown are neutral colors and pair well with any color in the color wheel. Try to avoid pairing green with purples or oranges, as these colors typically clash.
