Green is life. Abundant in nature, green signifies growth, renewal, health, and environment. With both a warming and cooling effect, the colour green denotes balance, harmony, and stability. Use several shades of green for a fresh, springtime feel. Olive green, also called olive drab, is a not so drab summery green that may have military overtones for some people. Green with blue produces echoes of nature - water and forest and can denote new beginnings and growth. Green with brown, tan, or beige says organic or recycled and can be a good colour combination for packaging of those type of products. Tri-colour combinations of green with yellow and black or white are sporty, outdoorsy colours. Purple with green can be high contrast, lively. Lime green with orange and yellow is a fresh and fruity palette.
