Your blueprints will be have bright red team colours. This is the default colour, before SE normally chooses a different one and spawns the ship in for you.

In the blueprints menu, you will need to use the folder icon to navigate into the "Economy - Red" folder (or whatever colour you chose). I create these folders so that the blueprints don't get mixed in with your own.

This script won't overwrite an existing blueprint. If you need to replace one, go into the Economy blueprints folder and delete it by hand first.

New version will prompt you to select the ship(s) that you want (it'll allow multiple selection) and to select a color. You can select these from the command line if you really like, but the interactive method works fine.

If you need different colours, just run the script multiple times.

Script now quits without doing anything if no colour is chosen. Simple way to abort.

Made the brown colour match the brown that you can sometimes get as a paint job on Economy ships
