Map between color names and RGB values
rgb = colorname(name) is the rgb-tristimulus value (1x3) corresponding to the color specified by the string name. If rgb is a cell-array (1xN) of names then rgb is a matrix (Nx3) with each row being the corresponding tristimulus.
XYZ = colorname(name, 'xyz') as above but the XYZ-tristimulus value corresponding to the color specified by the string name.
XY = colorname(name, 'xy') as above but the xy-chromaticity coordinates corresponding to the color specified by the string name.
name = colorname(rgb) is a string giving the name of the color that is closest (Euclidean) to the given rgb-tristimulus value (1x3). If rgb is a matrix (Nx3) then return a cell-array (1xN) of color names.
name = colorname(XYZ, 'xyz') as above but the color is the closest (Euclidean) to the given XYZ-tristimulus value.
name = colorname(XYZ, 'xy') as above but the color is the closest (Euclidean) to the given xy-chromaticity value with assumed Y=1.
