These are the colors I use for underlining favorite verses in my Bible. You uber-organized Aspies might like to try it. It helps me really think about the verse as I select which color to use.
As I was searching for images of Bibles, I picked this one because my middle name is Rose. When I enlarged the thumbnail, I was surprised to see that this Bible was open to John chapter 10 - my favorite passage of Scripture. John 10 is about Jesus being my Good Shepherd. Now I call that a "God-wink."
