Sunlight is a mixture of wavelength so is effectively white.


Sunlight starts out as high energy gamma rays produced by fusion reactions in the core.

It takes a photon many thousands of years to get from the core to the Sun's surface. It gets absorbed and re-emitted many times. It becomes lower in frequency in the process.

Light leaving the Sun's surface covers much of the spectrum. Much of it is infrared, visible: red, orange, yellow, green, blue, indigo, violet and ultraviolet.

The sunlight we see is a mixture of all of the colours and is white light.
