The 172 is "Earth Green", but it doesn't really look all that green to me.

I really like these pencils otherwise, so it's a real bummer I have to use greens from other brands for landscapes and stuff like that.

Here's some pencils with highest lightfastness one could add to complement a Pitt Pastel Pencils set:

Caran d‘Ache:
039 Olive Brown
212 Chromium Oxyde Green
245 Light Olive 40%
711 Earth Green
712 Verdigris
719 Dark Phtalocyanine Green
736 Brown Olive 50%

Derwent:
P460 Emerald Green

Their own Polychromos colored pencils don't have this issue.

If you want to draw landscapes, you have to get some extra greens from Derwent or Caran D'Ache. That's not what I expect from a 100+ euro pencil set for artists.

Willow charcoal, Winsor & Newton medium charcoal pencil, and General's Charcoal White pencil on gray Canson Mi-Teintes paper (A4).
