Colour Mixing
There are three types of color mixing models, depending on the relative brightness of the resultant mixture: ''additive'', ''subtractive'', and ''average''. In these models, mixing black and white will yield white, black and gray, respectively. Physical mixing processes, e.g. mixing light beams or oil paints, will follow one or a hybrid of these 3 models. Each mixing model is associated with several color models, depending on the approximate primary colors used. The most common color models are optimized to human trichromatic color vision, therefore comprising three primary colors. Mixing models Additive model Additive mixing combines two or more colors into a mixture with brightness equal to the ''sum'' of the components' brightnesses. An ideal physical model to demonstrate the additive model comprises two superimposed colored lights aimed at the observer. The additive model is usually demonstrated by reflecting two beams of colored light off a white, matte surface (e.g. projec ...

Oil Paint
Oil paint is a type of slow-drying paint that consists of particles of pigment suspended in a drying oil, commonly linseed oil. Oil paint also has practical advantages over other paints, mainly because it is waterproof. The earliest surviving examples of oil paint have been found in Asia from as early as the 7th century AD, in examples of Buddhist paintings in Afghanistan. Oil-based paints made their way to Europe by the 12th century and were used for simple decoration, mostly on wood. Common modern applications of oil paint are in finishing and protection of wood in buildings and exposed metal structures such as ships and bridges. Its hard-wearing properties and luminous colors make it desirable for both interior and exterior use on wood and metal. Due to its slow-drying properties, it has recently been used in paint-on-glass animation. The thickness of the coat has considerable bearing on the time required for drying: thin coats of oil paint dry relatively quickly. The vi ...
