I find the colors in Akkerman line nice however I was disappointed when they discontinued the big bottles.
Anyway even when they're small, the Akkerman bottles rock.
Hopjesbruin is very nice brown that I enjoy. On the other hand I believe and will try to prove it that Hopjesbruin is just repacked Diamine Sepia.
