YSL grey colors - Fog and Earth

  1. I'm looking for a grey Loulou but I can't seem to figure out the true colors of fog and earth. I have a fog sac de jour and I know it's more a warmer grey. Whilst looking online (particularly Farfetch) Earth looks more like a llight to medium cool toned grey. But some photos show it as quite a dark grey.
    - Here's what I found from Farfetch that is Earth:

    - Lastly this in Storm

    Storm is a bit dark for me, but I'm looking for a cool toned grey bag. Can anyone tell me if the photos on Farfetch show the true colors please? Thanks
