Ive seen a few guys on here do some pretty impressive stuff with LED's and was hoping some one could give me a bit of advice with my project.
Im planning on running either 10 or 20 Green LED's on the bottom of a skateboard im going to be making. I have the mounting figured out for the most part.
Im planning on using a 9V battery as the supply, but should I run them in parallel or in series?
Id like to do Blue LED, but cant seem to find them, should I stick with green? is green simpler? I know green requires less Forward Voltage.
This site shows them run as a large parallel composed of smaller series.

Any advice you guys have?
I have a basic understanding of circuits and circuit elements, but real world apps of LED's werent covered in my electrical engineering class haha.
