If you make your designs in Inkscape you could use this palette I made based on the colors of LightBurn.
I included instructions where to save the palette in the readme.txt (for windows and mac).
After installing the file (and restart of Inkscape) you can select the ‘LightBurn’ pallette on the right bottom of your screen, next to the colors.
You can download this from https://twenspace.nl/files/color_palette_lightburn.zip
(can’t upload it here).
