netbeans: how to disable the automatic text diff?

I am using NetBeans for some java projects that are under Subversion scm. Whenever I editsomething, Netbeans (6.9.1) starts adding colored lines, both in the left and right margins. That, combined with the other colored indicators it adds for like anything I can think of, is driving me insane. I know it's almost christmas but I don't want my editor to reflect that.

How do I disable this diff completely?开发者_如何学JAVA

How do I completely disable all coloring/hints/... except for syntax coloring of code?
