Brightness and Colour Matching

What I believe to be an important practical application of SHV follows from the proven accuracy of the simulation of visual sensing of changes of brightness & chrominance. An important industrial requirement, particularly concerned with the textile industry, involves the accurate matching of brightness, both for neutral shades & colours. It seems that this is a procedure which is still normally carried out by highly trained observers, which in turn means that it must inevitably be subject to some extent to uncertainties associated with observer subjective decisions.

It has recently been shown that it is possible to achieve a very high and reproducible brightness & colour matching by the use of SHV, utilising essentially the same test conditions & standards presently employed for visual assessment. As such, this should have the potential to remove the inevitable uncertainty in subjective assessments. A short discussion document was produced on the subject.
