I am triyng to decide whether to make my blade el or led.I am new to this and have many friends who want them made for them as well, so I want to get it right.We fight very hard with midevil weaponry & armor, all of which I custom make & now we want to get into this as well.

Anyway,sorry I tend to rant...My question is I am slightly color blind and wish to know the colors of the discs in order on the picture. I am color blind but my friends are not, dont want to look like a fool passing around my blue lightsaber that is purple...Also, it says you must "drop them between the blade and led lens", so you can simply take the blade out and quickly change it or is it more involved?

Thank you and sorry I sound like the ultimate newbie,
Cain
