Colour metrics that calculate euclidean distance between colours in different colour spaces.
euclideanLUV(colour, colourList, tolerance = Inf)
euclideanRGB(colour, colourList, tolerance = Inf)
euclideanDistance(spec, list, tolerance)The colour metrics return a matrix of distances, with one row per colour specification and one column per colour name.
An "sRGB" colour object representing colours to find a match for.
An "sRGB" colour object representing a list of colours to
find a match within.
A numeric value indicating a range beyond which matches will not be accepted.
A single colour specification, as an RGB vector of three values.
A list of colours, as an RGB matrix with three columns.

euclideanLUV() calculates euclidean distance in the CIE Luv
colour space.
euclideanRGB() calculates euclidean distance in the sRGB
colour space.
euclideanDistance() is provided as a helper for defining
euclidean metrics in other colour spaces.
