It's awesome mermaid hair!! I can't wait till I move and go through this whole home selling/home buying thing and can mess with my hair again (I just figure a more professional appearance might matter, but maybe I'm overthinking-- either way, just tossing John Frieda on once a month is infinitely easier) because I want to get a bottle of Sonic Green and see if I can come close to replicating your color.

I've done some Fishbowl/Electric Blue homebrews that give you a peacock blue, but I've never tried mixing Fishbowl with a green. BTW, if you haven't ever done it, SFX mixes can come up with some really interesting colors. Or layering a streak next to a color that would blend well with it so that you end up with a mix as you wash your hair and they fade over time. Colorful hair dyes are so much fun!
