I think your hair is fine just the way it is. Actually, the blonde doesn't look bad at all. You could always leave it. But I love funky colors myself. Just got my turquoise/green removed for job interviews. (Yuck!) I miss the days when I could put six colors in.Boy did that look cool. I did it for a modeling thing, so it was professional...but still. Lol.
Do you, Jason.Whatever makes you happy. Good luck getting that brown out!
oh! And post pics to update when you put the green back in!
