Need hair coloring advice

I'm really hoping someone can help me out with this. I've been having my hair colored at a salon for many years. Moved to a part of the country where salon color is very spendy, to say the least. I'd like to try to do my own color. I'd like to try L'oreal Feria color, because it's supposed to give your hair a highlighted look, and got rated pretty good, on the online reviews.

My hair was last colored and highlighted in May. My hair is naturally dark brown, and is colored a couple shades lighter with med. blonde highlights.
Not bleached highlights. I want to use a light brown color, but my concern is that my highlights may come out orange looking. I've been researching online for advice, and there's a lot of conflicting info. I did see in a couple places, that if you go with a darker shade than your highlights it should work out okay. Also, I've seen where some women have ended up with green hair too. (Yuk) Any advice would be greatly appreciated. Thanks !

Thanks for your advice. I appreciate it. I've decided on a color to use, Clairol Nice and Easy, Natural Lightest Golden Brown. I've been using the Clairol Light Brown root touch up for a couple of months now and looks good. So, I'm hoping when I use the all over color it will work out well. I haven't colored my own hair for over 20 years so, it's a little scary. Are you a hair stylist, or are you just knowledgable about hair color?    Debbie W.
