what colours of bohyme would this be?..

The second picture looks darker, but I am sure it's all a matter of light.

If you want to take the golden out of your extensions you might want to tone it yourself because most of Bohyme blonde colors come in golden rather than ashy colors, I think it is true of a majority of blonde extension hair for some reasons...

I like the color 14B, it is much lighter than 14 and looks a lot like some of J.S.'s lowlights on the second picture. 14B and 16 both lose their gold tones after 6 or 7 shampoos and blend better.

I wear a mix of 16/14B/24 and it my extensions looks less golden after the firt few days of my first install.

Another idea: check out the "bohyme blonde" line, sold on ebonyline and  and maybe hairsisters. It's a specific line that sells ashy blonde if I remember well, the hair is more expensive than their "regular"  gold & platinum line.
