Colour and appearance attributes

Abstract

Object appearance involves all visual aspects, namely colour, gloss, shape, texture, shininess, haze, transparency, etc. Wavelength-specific light phenomena are responsible for colour, while geometric or directional selectivity is primarily responsible for gloss, translucency and similar attributes. The geometric attributes, namely diffuse reflectance and transmittance, affect the colour of an object significantly. Various geometric and colour attributes and their assessment methods are discussed. Colour combination schemes and their emotional aspects are explained.
