Teal dye suggestions please?

Turq over a very yellow, maye nearly orange base should achieve that. Or very diluted Alpine forest by MP. I'm prety sure mine faded to almost that. Or alpine and atlatic mixed and diluted would make ^that^ but shimmery =D

Yep, I agree with diluted Alpine and then experimenting with adding blue (it's a lot greener than it used to be).

Thanking you! I might just have to experiment. So annoying when these pretty colours happen by accident!

I used the pravana chromasilk vivids line.  Their 'green' is actually more teal, and adding just the tiniest bit of their blue to the mix can help~
My profile picture and the pic I'm linking below is my hair on the same day in different levels of light.

Now, I'll warn you. My hair was a very deep blue that I bleached over and it turned almost neon. So I just put the Vivids green in my hair for about 3 hours before rinsing.  Luckily, it had the desired effect which was a very pretty teal with varying shades of blue throughout.  I love the Vivids dyes but they are very tenacious.  It takes so much effort just for me to get rid of them. 
I hope this helps a bit, and even if it doesn't I really hope you can get to the color you want. (It's a very lovely color to have)

I second directions turquoise over yellow-orange, the last batch faded very teal on my yellow hair and even more teal where its less bleached.
