The strict 2013 Anthracite bags have very little to no green undertone. However, I also think they have very little blue undertone either
and in that case, why get Anthracite vs Gris Tarmac? They are nearly identical.
If you go with Anthracite my suggestion is to fully embrace the variety of tones. I take pictures of my bag and it looks navy in one, teal in another, and hunter green in a third. The crazy mix of shades is part of what makes Anthracite what it is. You may be happier with a plain gray if you really dislike color tones, but, that's just me.
One of my favorite gems is labradorite and I love how my Balenciaga can capture all the crazy facets that my jewels do
