Again I would recommend a search in Google images. Here are just a few examples that I found in less than 2 minutes.... of a picture is worth 1k words.... here are a bunch of words. Happy hunting. The options are literally endless.
If your asking about a accent color purple or orange would work great. Don't limit your search to jeeps custom bike builders also use the bold colors that jeeps can use. I remember one biker build off show where the paint was green and tangerine and looked amazing.
