How does colour psychology work? Colour is light, travelling to us in waves from the sun, on the same electro-magnetic spectrum as radio and television waves, microwaves, x-rays etc. Light is the only part of the spectrum that we can see, which perhaps explains why we take it less seriously than the invisible power of the other rays.
Sir Isaac Newton demonstrated that light travels in waves, when he shone white light through a triangular prism and the different wavelengths refracted at different angles, enabling him to see the colours of the rainbow (the spectrum).
When light strikes any coloured object, the object will absorb only the wavelengths that exactly match its own atomic structure and reflect the rest - which is what we see. Turn this around and it is easy to understand how the colour of anything is a clear indication of its atomic structure or, in simple terms, what it is made of.
When light strikes the human eye, the wavelengths do so in different ways, influencing our perc
