Hair disaster! I really need a home remedy fast please.?

I naturally have dark blonde-light brown hair that I have professional hi-lights/low-lights put in every 3 months. Due to a very busy schedule these days I decided to add an all over box color of light ash blonde just to the re-growth. This changed the roots to a reddish color- not matching my mostly blonde/light brown hair. So, I bought a hi-lighting kit knowing that it would lighten it up and applied it with a comb and didn't leave it on long enough- it turned it a bright apricot color. The next day I repeated that same process, but left it on for the recommended time= now I have 3 inches of a bright yellow (think banana popsicle) hair- starting at my roots. The bottom half of my hair is fine. I know the best option is the salon, but no one can fit me in for at least 2 weeks. Would adding an allover color to my entire head of light ash brown or blonde work? Would my hair turn green? I am using Aveda's Blue Malva shampoo to try an balance the briness, but it's not helping.
