Help me choose a dipbrow shade? [Product question]

I'd really like to take the plunge and order dipbrow, however the nearest sephora is over four hours away and I'm in Canada, so I can't run out to swatch it and a lot of swatches online look very different based on skintone. I have dark brown, slightly reddish hair and fair skin with very sparse brows and currently use an ELF cream eyeliner in brown, and I think the color match is reasonable. I'd like to upgrade though, since it can be a finnicky formula.

Here is a photo of my hair color. I was thinking Chocolate at first, but now I think that's maybe a little too dark. http://i.imgur.com/HUeLhui.jpg
