Discover the 7 Colours of the Rainbow in simple words. Learn each rainbow colour name, meaning, and usage to boost your English vocabulary.
Have you ever looked up after a rain shower and seen that magical arc of colours painting the sky? Those Colours of the Rainbow have fascinated people for centuries, not just because they’re beautiful, but because each one has its own meaning and name. In this post, we’ll explore all seven colours of the rainbow in simple words, so English learners and educators alike can enjoy both their beauty and their vocabulary.
What Makes a Rainbow Appear?
A rainbow appears when sunlight meets water droplets in the air, usually after a rain shower. The light bends (this is called refraction), then splits into different colours (called dispersion). Finally, the light bounces back from the inside of the water droplet (reflection) and reaches our eyes.
This process creates a beautiful arc made up of seven colours of the rainbow, always in the same order: red, orange, yellow, green, blue, indigo, and violet. The rainbow we see is actually a full circle of light, but from the ground, we only see the top half.
Fun fact: You can also see rainbows in the mist from waterfalls, fountains, or even in the spray from a garden hose on a sunny day.
The 7 Colours of the Rainbow in Order
The Colours of the Rainbow always appear in the same sequence because of how light is split into different wavelengths. Starting from the top of the arc, you’ll see red, the boldest and most visible colour. Next comes orange, a warm and cheerful blend of red and yellow. Following it is yellow, bright, and sunny, like the midday sun.
In the middle of the rainbow sits green, a colour that feels calming and fresh, reminding us of nature. Below green is blue, cool and peaceful like a clear sky. Then comes indigo, a deep and mysterious shade that lies between blue and violet. Finally, at the bottom, you’ll find violet, soft yet vivid, adding a magical touch to the rainbow’s beauty.
To remember this order, many people use the acronym ROYGBIV, which stands for Red, Orange, Yellow, Green, Blue, Indigo, Violet. This is a simple and useful tool for English learners who want to memorise rainbow colour names.
