 NearestNamedColor - Maple Help

ColorTools/NearestNamedColor

find the closest color with a name Calling Sequence NearestNamedColor(color, opts) Parameters

 color - color format recognized by ColorTools opts - (optional) equation(s) of the form option=value where option is one of metric, new, number, palette, or threshold Options

 • metric=string or name : the type of color distance to use
 • new = truefalse : option passed to GetColorNames if palette is not specified
 • number =  posint : the maximum number of nearby colors to return
 • palette : a palette or palette name, a list of palettes and/or palette names, or "all"
 • threshold = float : a maximum distance.  If number is not specified all results closer than this value will be returned. Description

 • The NearestNamedColor command locates one or more of the nearest named colors to the input color.
 • It returns one or more named colors, along with the distances from the input color. When there is only one result, that single nearest color name is output, along with the distance in the specified metric (cie94 by default).
 • When the number of outputs is greater than one, then the output is a list of the nearest colors and distances, closest first. Examples
