Parameters:ncolors (scalar) – Optional. The desired number of colors for a specific palette. Default value is 6. If ncolors is fewer than the minimum number of colors offered by a palette, then the minimum will be returned with a warning. The same behavior occurs when ncolors is greater than the maximum number of colors a palette supports.
Returns:clrs (ncolors x 1 string array) – hex values for each color in the palette.

Examples

Basic Usage

// Get the first 3 colors from the ColorBrewer 'Dark2' palette
clrs = getColorPalette("Dark2", 3);

After the above code, clrs should equal:

#1b9e77
#d95f02
#7570b3

These string values in clrs are hex values that describe RGB colors. They can be passed directly to any of the GAUSS plotSet functions which take a color as an input.
