What Colour Is the Actual Sun
The sun is one of the most fascinating natural wonders we have, and while most of us have seen it with our naked eyes, few know what colour it appears to actually be. So, let's dive into the science behind what colour is the actual sun.
Fundamentals of Light and Colour
What Determines Colour?
Colour is a phenomenon that occurs when light with various wavelengths enters the human eye. Visible light includes an array of wavelengths covering the spectrum, ranging from violet frequencies to red frequencies. The colours we perceive are a result of the light scattered by different materials or absorbed by them.
Is the Sun White, Yellow, or Something Else?
From a physicist's point of view, the most accurate description of the sun's colour would be that it doesn't have a single colour but rather emits all the spectrum of visible light equally. However, the sun's colour as seen from space is accurately described as white.
From Earth's surface, thanks to atmospheric scattering, our perspective changes due to the scattering of shorter wavelengths of light. This scattering effect gives our view of the sun a yellowish hue. The Earth's atmosphere acts as a filter, filtering out the various colours and displaying them to our eyes according to their frequency. This is why we perceive the sun from day to day in different light conditions as various shades of yellow.
