How to display all the available colour tables - PDLPorters/pdl GitHub Wiki
Here is a Perl one-liner to display all the available colour look up tables in PDL::Graphics::LUT
perl -e 'use PDL;use PDL::Graphics::PGPLOT;
use PDL::Graphics::LUT;dev("/xs",3,15);
foreach(lut_names()){print"$_\n";ctab(lut_data($_));imag sequence(250,1);
text $_,20,-0.2,{CHARSIZE=>20,LINEWIDTH=>20,COLOUR=>0};
text $_,20,-0.2,{CHARSIZE=>20,LINEWIDTH=>1,COLOUR=>1};}'
This produces a PGPLOT window with all the colour tables labelled with their name.
To just see a list of available colour tables, use:
perl -e 'use PDL::Graphics::LUT;foreach(lut_names()){print"$_\n";}'
