How do Humans See Colour?
Three different types of Cones locaed in your eye are responsible for our ability to see colour. Each type of Cone is sensitive to a different wavelength range, corresponding to Blue Spectrum (Short), Green Spectrum (Medium) and Red Spectrum (Long). Humans see a small portion of the electromagnetic spectrum, from about 400 nm to 700 nm. Coloured light takes a detour over the surface of an object.
Metamerism, in Colourimetry, is the matching of colours that are perceived with different (nonmatching) spectral power distributions.
In the paint industry a “good match” attempts to allow for two colours to look similar in various light sources that may be present in the areas where the paint could be coated. Fluorescent or incandescence’s for example. For best results, it is best to use the same pigments that were used in the original colour when matching if at all possible. Many times, this is not possible or known.

Datacolor Spectrophotometers Measure & Evaluate Colour
They are part of a broader colour computer program to capture and communicate the accuracy of colour samples and their matches or reproducibility. At PROTEK Paint, a spectrophotometer is used to measure many various types of samples to deliver the desired colour.
To match colours at Protek Paint we use a Datacolor Spectrophometer that incorporates the CIE colour model, or CIE XYZ colour space, CIELAB, where L refers to luminance, A the red/green axis, and B the blue/yellow axis. Yet another model, CIE L*C*h, factors in lightness, chroma, and hue. CIE is a mapping system that plots colours in a 3D space using red, green, and blue values as the axes.
