Electromagnetic waves interpreted as colours
The speed of light is equal to its frequency times wavelength
The frequency is inversely proportional to wavelength
And that is exactly why light has constant velocity
300 million meters per second
In a vacuum
Take a look at the light spectrum
Which shows only a small fraction of the light that we get from sunlight
All its rainbow colours are absorbed to make the colour black
And they are all reflected in order to make the colour white
