My red hair dye came out purple help!?

So I wanted to go from black to red right? So I stripped my hair to get some of the black out, and it worked It dulled it down to a reddish-brownish color that was pretty coppery, which is pretty typical of a successful stripping, this much I know. Then I dyed over it with a permanent dark auburn. The color seemed to be rather red/brown based. It didn't look purple on the package, and didn't look purple in the bottle. But for some reason it came out a rather burgundy/purple shade (most obvious at my roots which are indeed lighter than the rest of my hair; I knew they'd be lighter and I'm okay with that. It's the tone I don't like).

Now, I need my hair to not be so purple. I don't particularly like the color, and when my boss sees it, he's not going to be thrilled in the slightest. I also don't really want to redye my hair. Though it appears to be in good shape after stripping and coloring (and it should be! I just cut most of it off), I don't want to push my luck, or go through the time and aggravation again so soon. So is there anything I can do to tone down the purple?

I'm not going to a salon. It's too expensive and I really don't have the time. My first thought was, hey, orange toning shampoo! That should counter the blue hues. But apparently, orange toner is not a thing. I've also hear I might try dandruff shampoo, or mixing 1 part 3% hydrogen peroxide with 2 parts shampoo. But I'm not terribly thrilled with either of these options, because I'd like to keep the red and brown hues, it's just the blue hues that have to go. So help me! There has to be something out there. Or will I just have to redye it, or pick up some sort of wash in color shampoo to cover the shade for work?
