Advice for Color Fix on Adore Sienna Brown + Copper Brown

I'd first like to say I used to use another semi-permanent by Clariol Professionals Beautiful Collection and I didn't like the overpowering perfume smell it gave off and the waxy coating it provided due to the jojoba oil.

So I did my research through this forum and saw that many people recommended Adore. (Thank you btw!) After days of going through online color swatches and photos I decided to do Adore Sienna Brown mixed with Adore Copper Brown, in hopes I would get a nice med red/brown auburn more on the brown side of undertones. However, after today's dying adventures... I feel like this is more light red with purple-ish tones. (See attachment #1, hopefully you can see what I'm talking about.) In the end, not exactly what I was hoping for. It might die down a little after the next wash... but I'm wondering if I should try to fix it myself because I'm scared it's going to lighten and I'll have a reddish purple-ish blonde.

So, a few questions for all you Adore users out there. #1, how many days after dying my hair the first time can I try to add more color to my hair? Without damaging it too much or causing fallout or anything. And #2, if I do add color what would you recommend I use to add brown to this color to make it a more brown auburn? I was looking at Mocha (although it still seems a little purple-ish), or one of the other browns (not Medium though, since I've heard from you guys it can go green). Also, I realize what might be best to put on it now to fix it might not be what you'd suggest to do from the get-go next time, so #3, any recommendations on which Adore to use to get it a medium reddish brown? (See example, attachment #2)

Any advice would be greatly appreciated!!

Also, for some background information my natural hair color is a light-to-med ash brown / dirty dishwater blonde. I had a light auburn semi-permanent color on it that faded out almost entirely except for some of the ends, so that was the base before this dye job.
