Orange is a colour that is associated with warmth, vibrancy, and energy. It occupies a special place in the colour spectrum, bridging the gap between red and yellow. But what exactly makes orange, orange? Where does this bright, joyful hue come from in nature? In this article, we’ll explore the origins, meanings, and uses of the colour orange.
What Makes Orange Orange?
In technical terms, orange is a secondary colour made by combining red and yellow. The specific shade of orange depends on the proportion of red to yellow used. More red gives a reddish orange while more yellow results in a yellowish orange.
On the light spectrum, orange has a dominant wavelength of around 610 nanometres. This wavelength stimulates our retina’s L-cones and M-cones but not S-cones, resulting in the perception of orange.
So in summary, orange is the colour the human eye sees when it looks at light with a wavelength of roughly 610nm. This light stimulates the red and green colour receptors in our retinas, mixing to form the orange sensation.
The Origins of the Colour Name
The word “orange” originated in the early 16th century, derived from the Sanskrit word naranga, which referred to the orange tree. This became naranj in Persian and Arabic, eventually becoming orange in English.
Before this, there was no specific name for the colour in English. Reddish yellow was just called “yellow-red”. The introduction of the orange fruit led to the distinct colour term we know today.
Natural Sources of Orange
Orange rarely occurs in nature as a pure spectral colour. But there are many natural objects and phenomena that display vivid orange hues, like:
| Natural Source | What Causes the Orange Colour |
|---|---|
| Carrots | Carotenoids like beta-carotene |
| Pumpkins | Carotenoid pigments |
| Oranges | Carotenoids |
| Autumn leaves | Carotenoids revealed as chlorophyll breaks down |
| Sunrise/sunset skies | Light scattering causing predominance of red/yellow wavelengths |
| Some flowers like marigolds | Carotenoid pigments |
| Monarch butterflies | Pigments called pteridines |
As you can see, orange in nature generally comes from pigments called carotenoids. These are organic compounds produced by plants, algae, bacteria and fungi. Chemically they are made of chains of isoprene molecules that can absorb certain wavelengths of light.
The most common orange carotenoids are beta-carotene found in carrots and alpha-carotene found in pumpkins. These molecules absorb bluer and shorter wavelengths of light, leaving behind the longer orange/red wavelengths to be reflected and seen.
Other pigments like pteridines can also produce orange shades in animals and insects like butterflies. So in summary, plant chemicals, light scattering, and animal pigments all contribute to orange colours in the natural world.
