You can reference colors in the palette by name or number in most commands that understand color names.
You can make Dalton the default palette in plots using setcolors
You can programmatically access the colors using ColorTools commands
ColorTools algorithms will automatically generate new colors beyond the main 10 colors. Extended colors are algorithmically generated and should also attempt to be well distributed for red-green color blind viewers.
The Dalton palette is designed for filled areas, but the Lookup command can provide slightly altered shades of its colors for use in coloring points or lines.
