Semi permanent recommendation to get from red to blonde hair?

Hi there hair color experts! I've been playing around with colors and was experimenting with being a red head (which I really liked). Now, we are finally going on a beach vacation and I tried to get my hair back to blonde and its not going so well.

These are the steps I took: I'm naturally dark Brown. Bleached hair then added a permanent Wella 8RG/729 all over head to be a ginger. Fast forward a few weeks, to get to blonde I added Wella Demi 8A-8/1 to cancel the warm tones (and provide more coverage than just a toner). Now I'm left with light roots and warm ends with orange and green undertones and no depth. My goal is pretty beach hair/with dimension or an even bronde color if necessary. Is there a demi permanent or toner you could recommend that would cancel out the red tones in my hair? Thank you!
