I don't know what to do!1

I hope this isn't too late to help, but put a semi-permanent color over it to tone it down.  Maybe a nice brown...if it's really really orange, then use an ash brown (blue base).  Even a neutral brown should take you to auburn.  Or a dark auburn would probably be more reddish because you're starting from orange.

Semi-permanent colors you can get from Sally's are Clairol Colorgloss, Clairol Complements, and Wella Colorcharm (be aware that the last two use the same name for both their semi and permanent lines).  I've used Colorgloss a lot myself and like it.  Just mix one part Colorgloss with one part Clairol Radiance developer (yeah, I think the name of the dye is actually Radiance, not Colorgloss, but that's what everyone calls it).

Good luck!

Ok... I have long, curly hair and I colored it dark brown in November. My roots grew in (light brown) about 1.5 inches or so. I decided I wanted to go light red (specifically Feria Copper Shimmer), and I asked a girl at Sally Beauty if I could, and she said I'd have to bleach my hair first. On Friday, I used Feria Extra blond bleach... my roots turned out bright yellow and the rest neon orange. Then Saturday, I used Feria Copper Shimmer, and my roots are NEON orange, and the rest of my hair is pretty close. I am freaking out, 'cause I have to go back to work tomorrow, and I cannot have neon hair!! :( I have to do something with it tonight, but I'm not sure what.. I thought maybe use a darker red shade, since it will probably turn out lighter red anyway? If anyone can help me out, please do!! I can't even go out like this.. I'll have to send my hubby out to buy the color!! Thanks!
