In menu: Colors ➤ Components ➤ Stack Layers By Colors...

    This plugin will make a copy of your active layer in a new image, then turn that image into indexed mode with number of specified colors, then for each color it'll make a copy of it and stack it on a new layer. So the result is that you'll have different colors stacked on different layers. Can be useful for screen printing.

Changes in Ver.3 introduced by MrQ:

-added layer names by color,
-remove selection,
-resize layers to image size,
-changed location in Gimp menu.
