Green #008000

Green is the color of plants, so its core meaning is life and growth. It appears on anything that wants to say natural, healthy, renewable, or fresh, from organic food labels to recycling programs and environmental groups.

It also means go. Traffic lights, status indicators, and success messages use green for safe or done, which gives it a practical, reassuring job in interfaces. In the United States, green banknotes tie it to money and finance as well. In much of Europe, a green cross marks a pharmacy.

Cultural meanings vary. Green is closely associated with Islam and appears on the flags of many Muslim-majority countries. Ireland uses it as a national color. In English it can also mean inexperienced, or envious, as in "green with envy."

This green works well for buttons, success states, and badges, and it's a dependable brand color for finance, health, and sustainability. White text reads clearly on it, which makes it practical for call-to-action buttons; black text is weaker. Because it is so saturated, a large field of it can look flat on screen, so many brands use it as an accent next to white, cream, or soft gray. Don't rely on green alone to signal success, since red-green color blindness is common. Add an icon or a label too.
