What is light?
Most
of the colours we see around us depend on the way in which white light
is absorbed or reflected by surfaces.
Snow scatters all the wavebands: that is why it looks so white.

Light
is only part of a series of electromagnetic radiations that differ only
in their wavelength. They range from long wave radio transmission through
television, radar, radiant heat and x-rays down to gamma wavelengths shorter
than a thousandth of a millionth of a millimetre.
Light rays themselves are not coloured but each visible waveband produces a different colour sensation in our brain.

The
ocean, like a mirror, reflects the blue sky in the same way that a ping
pong ball bounces off a table.

"Colour helps to express light, not the physical phenomenon, but the only light that really exists, that in the artist's brain."
