Given a current Measure, the Colour Matching function displays the 5 most similar colours, looking
up the References list or a subset of it. A proprietary or standard database (RAL classic and RAL
design) can be used as the Reference list. The closest matching colors are ranked by increasing
CIELAB colour difference with respect to the current Measure. This information can be used to
select the colour that resembles the measured sample by simply checking a best-candidate colour
palette instead of looking up a large set of physical samples.
