Hair repair

I fixed my dark roots over the weekend, with a different brand of highlighter than I've been using. It came out very light, almost white blonde. Just not a flattering color for me. So I used the brown rinse that I got the last time I screwed it up (though that time it was a really hideous brassy orangey blonde). Now it's toned down and looks more golden in regular light, but in the flourescents at work, it has a distinctly greenish tinge. Maybe I should quit doing this myself and get it done professionally!
