Light & Colour
Articles exploring the 2-dimensional polarity of light and dark and the 3-dimensional world of colour. The various theories of colour and the development of abstract colour spaces for mapping and identifying colours. The unique position of grey in colour space and the concept of achromatic colours.
We explore the nature of coloured materials and how illuminants and surfaces interact. The perceptual world and the visual processes including optical illusions and colour constancy. We take a look at the geometry of shadows, the umbra and penumbra, the principles of reflection and refraction and finish with a crash course in optics.
