Introduction
Green is one of the most powerful and universally recognised colours in human history. Often associated with life, nature, growth, and renewal, green colouring has shaped art, culture, fashion, food, and even psychology.
From ancient natural dyes made from plants to modern synthetic pigments, the story of green colouring is as rich as the colour itself.
But green is not just about aesthetics—it influences mood, branding, sustainability, and even health. Understanding the science, symbolism, and applications of green colouring allows us to appreciate its timeless importance in human civilisation.
This guide explores everything you need to know about green colouring: its natural origins, cultural meanings, modern applications, and future innovations.
The History of Green Colouring
Early Natural Pigments
- Ancient civilizations derived green pigments from plants and minerals.
- Malachite, a copper carbonate mineral, was ground to create vibrant green paints.
- Medieval Europe relied on verdigris, made by exposing copper to vinegar.
Green in Ancient Cultures
- Egyptians used green colouring in tomb paintings to symbolize rebirth.
- In China, jade—a green stone—was revered as a symbol of purity and immortality.
- The Romans wore green clothing to represent fertility and harmony.
Challenges in Creating Green Pigments
Historically, green was difficult to produce and preserve:
- Many early pigments were toxic (e.g., arsenic-based greens).
- Colours often faded or darkened over time, making stable green dyes rare.
The Science Behind Green Colouring
How We See Green
- Human eyes perceive green due to the medium wavelength of light (~495–570 nm).
- Green sits between blue and yellow in the visible spectrum.
- It is one of the primary colours in additive colour mixing (RGB).
Natural Sources of Green Colouring
- Chlorophyll in plants is the most common natural source of green.
- Minerals like malachite and celadonite have long been used in art.
- In food, natural green colouring often comes from spinach powder, spirulina, and matcha.
Synthetic Green Pigments and Dyes
- Chromium oxide green is widely used in paints.
- Phthalocyanine green provides stability and vibrancy in plastics and textiles.
- Food industries use E141 (copper chlorophyllin) for safe green colouring.
