What color lightsaber would you want?

Not only do the aches and pains get worse...but injuries don't heal as well either. I have a severe shoulder injury that will never stop hurting.....sure plays hell with lightsaber action...lol....oh....a query...Does the color pick the jedi or do the jedi pick the color? I know in Harry potter, the wand picked the wizard.....so I was wondering about the color of the blade........
