question about dying hair red

hey guys! well i've been wanting to dye my hair red, kind of like a dark auburn or a plum color. something like this:

 or

anyways my hair right now has been dyed to a dark brown with blonde and brown highlights. i was wondering how long the red color stays on for because my friend told me it doesn't stay on for long and starts to fade after a while. oh and if it fades what color does it turn? thanks for any help!

I did the burgundy colors when I was in high-school. They do fade really fast, and I always ended up with orangey-brown hair after a month or so. I agree with the advice about dying over highlights. You will have uneven color and some areas will probably turn out a bit funky.
