Returns the RGB triplets of the given list of named colors.

Available in version 6.0.0 and later.

Prototype

	function namedcolor2rgb (
		colors [*] : string   
	)

Arguments

A string array of named colors.

Return value

A float array of size n x 3 is returned, where n is the number of named colors input.

Description

This function returns the RGB triplets of the given list of named colors. If any of the input colors are invalid, missing values will be returned for that triplet.

Note: this function will be moved from "gsn_code.ncl" to "utilities.ncl" in NCL V6.4.0. This shouldn't have any affect on your scripts, since these two scripts are automatically loaded by NCL. To use this function with older versions of NCL, you must load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl" at the top of your script.
