The natural world is full of colours, seen in humans, plants, and animals. And they do much more than make the world beautiful—they help living things survive and connect with each other. Let’s explore how colours work their magic.
Human skin comes in different shades(色度), which is influenced by sunlight, emotions and health. When we feel strong emotions like anger or excitement, our skin can turn red as a result of increased blood flow to the face. Therefore, people often say “seeing red” when someone is angry.
Plants also use colours to survive. Flowers have bright colours to attract insects like bees, which help with pollination(授粉) by spreading pollen from one flower to another. These insects see colours we can’t. Without them, many plants would struggle to survive.
Animals are colour experts, too. Some change their fur or skin colours to blend in with their surroundings and avoid being seen by predators(捕食者). For example, the snowshoe hare changes its fur from brown in summer to white in winter to match with the snow and hide from foxes and wolves. Others use bright colours to warn predators to stay away.
Every shade in nature has a purpose. They help humans share emotions, let plants grow new life, and protect animals from danger. Whether it’s a blushing cheek, a blooming flower, or a hidden hare, colours are nature’s secret language—a language that keeps our planet full of life and wonder.
