GreenYellow

Green is restful and reassuring. It is strongly tied to health, growth and money, and because the eye processes green easily it can reduce visual fatigue and promote a sense of balance.

Green is everywhere in health, wellness, finance, environmental and organic brands. It works for success states and confirmations in UI, and its many shades range from fresh spring accents to deep, premium forest tones.

Greens were historically difficult to produce; early pigments like verdigris and malachite were unstable or toxic. A breakthrough came with Scheele’s green and later chrome green in the 18th and 19th centuries, which popularized the color despite some toxicity concerns.

Green symbolizes nature, renewal, safety and prosperity across most cultures. It also means “go” in signaling and is the color of many environmental and religious movements.

Choose green for brands that want to feel natural, healthy, trustworthy or financially sound. It is a versatile hue that works equally well as a calm background or a vibrant accent.
