Merely reading its name, forest green will likely evoke visions of thick bushes and tall trees. Named for that exact type of scenery, forest green is a dark green hue commonly found in nature.
Often associated with the environment, forest green has been used for designs related to causes supporting the earth and its ecosystem. As forest green’s most direct complementing color is a bright red, it can often also evoke the Christmas holiday when used together. To avoid that association, you can use forest green to accent blues and greens.
