Thats a good start:)
Then you can find the folder on your computer where you have the template and copy the folder as many times as you need it and name it ja_teline_red, ja_teline_blue and so on. Then open up the template folder for each of them and find the file templateDetails.xml, and change the names i marked in red. Remember if you have folder ja_teline_red that you give the name of the template in the templateDetails.xml the same name:
<?xml version="1.0" encoding="utf-8"?>
<install version="1.5" type="template">
