// From the "Create" Menu, create banks of voxels in graded colours for use as a simple paint palette. Where ever your avatar is standing.
// Run all colour bars from the Create Menu and then use eyedropper tool to preselect all the colours you want on the UI, then select Remove All Palettes from the Remove menu.
// It is recommended to [create palettes, preselect colours on UI, run "Remove" function] without moving, as once you move from the create position the remove will not work,
// and you will have to delete the palette voxels manually. 
 
// Function that adds two categories to the menu.
