Color and appearance instruments are used to measure the properties of paints and coatings including color, gloss, haze and transparency.  Appearance is the manifestation of the nature of objects and materials through visual attributes such as size, shape, chroma, color, texture, glossiness, haze, transparency, opacity, hue, luster, orange peel, translucency, etc.

Color and appearance instruments generally fall into one of four categories, colorimeters, densitometers, spectral cameras, and spectrophotometers.  Colorimeters measure color using three or four filters that match human color receptors.  Colorimeters can show L, a, b or L*, a*, b* numbers but can only measure in one light source.  Densitometers measure the density of ink films using one or more filters.  Densitometers do not give complete color information, but are useful for specification and control of printed colors.  Spectral cameras provide measurements with full spectral and spatial information.  Spectrophotometers operate on the principle of reflected light.  Spectrophotometers measure individual wavelengths and then calculate L, a, b or L*, a*, b* values from this information.  These color and appearance instruments can measure in all standard illuminants.
