The effect COLOUR ALCHEMY has on the hair is a replication of structural colour – a visual effect or elemental phenomenon that can only be found in nature and complex molecular anatomies. Think of the spectacular, shimmering iridescence of the scarab beetle, a peacock's feature or the wings of a butterfly.
Unlike static pigmented colour each COLOUR ALCHEMY shade scatters the light in a range of kaleidoscopic hues, which transform in response to temperature. This process is illustrated by the rainbow spectrum bursting from the 'prism experiment'.
If a beam of white light is passed through a prism, a spectrum of different colours can be seen to emerge, including Red, Orange, Yellow, Green, Blue, Indigo and Violet. This is the visible light spectrum as we see it; each of these colours has its own wavelength within the range of 400 – 700 nanometres.
The prism refracts light, enabling white light to separate into its individual components. A similar effect can be seen in a rainbow: when it rains, water droplets in the air refract the rays of sunlight; the curvature of the Earth produces the bow effect we are so familiar with.
