==Syntax==
:{{tlc|ChartColors|''color palette''|''number of colors''|''show the color number''}}

{{ChartPalette}}

The ''number of colors'' must be from 1 to 20 (''Categ20'') or 26 (''Plotter'').

''Show the color number'' is an optional parameter, with two values: '-' the color number and 'a' with the degree of transparency ([[alpha channel]]) added at the end of the number and always it will be 'ff'. It is only interesting to add the color for the [[Wikipedia:Coloring cartographic maps|map coloring]].
