The ColorTools package contains functions for working with and converting colors, and doing conversions for: color names, internationalized color strings, hex color codes, decimal RGB sequences, and float sequences.

The core color type is the decimal RGB sequence, and can be used as a central point for conversion from one type to another.

The following is a list of the color formats handled by ColorTools

RGB24   - 24 bit RGB, integer values 0-255: [r,g,b]

RGB     - Float RGB values 0.0-1.0: [rf,gf,bf]

Hex     - Hex code in string form, e.g. either "#rrggbb" or "rrggbb"

Name    - Named colors, old: 'black','BLACK' or new: "Black"

String  - International strings - string form of Name but translated with GetMessage

PlotColor - COLOR primitive for plots: COLOR(RGB,x,y,z)

Color   - A data structure encoding other color spaces. It is detailed in ColorTools[Color].

Hex/Name/String convert to/from RGB24 values, so to convert from xxx to yyy usually one must convert xxx to RGB24 then RGB24 to yyy.

The Color datastructure generally uses floating point RGB for intermediate calculations to avoid loss of precision from the 8 bits per channel restriction of RGB24.

The ColorTools package was introduced in Maple 16.
