ISCCNBSblock: An ISCC-NBS Colour Metric

Description

A colour metric based on the ISCC-NBS System of Colour Designation.

Arguments

colour

An "sRGB" colour object representing colours to find a match for.

…

Other arguments passed by the colourMatch function from the roloc package.

Value

A matrix of distances, with one row per colour specification and one column per colour name.

Details

All colours and all if colourList are converted to an ISCCNBS block. The distance between a colour specification and a colour name is 0 if both are within the same block or Inf if they are not in the same block. It is also possible that either the colour specification or the colour name does not correspond to any block (could not be converted), in which case the distance is NA.

Examples

# NOT RUN {
colourName(palette())
colourName(palette(), colourList=ISCCNBScolours)
colourName(palette(), colourList=ISCCNBScolours, colourMetric=ISCCNBSblock)
# }
