Keep in mind it is very easy to heavily modify just the pen colors and only slightly modify the rest of the picture's colors. And all of that can be adjusted independent of the white balance. While I generally agree with the point you make, we have to be careful with our expectations based on these kinds of product shots. This kind of photoshopping is very frustrating because it creates so much uncertainty. I've been close to canceling my order a couple of times already actually...
And we've only been talking about the color. I'm sure the saturation has been jacked up (especially on the greener one!), and I'm betting the brightness and contrast have all been tampered with too...I'm hoping some real world photos come out before my order is processed so I can cancel if I end up not liking it.
I think it's a matter of being run through two different systems with different color management schemes. The greener of the 2 shows less detail in the colored bits in the swirl - looks to have driven it out of gamut - that could also be due to a saturation boost, which also may have been induced by the path the file took through different O/S and or different browsers.
Of course we'd like to see pix taken in the wild, accompanied by verbal descriptions that indicate what might be too subtle to see on screen.
Personally I'd prefer the Renaissance Brown to this - but I certainly like a tropical ocean palette. Additionally when I think of allocating precious resources I prefer vintage over current production, not that I couldn't be tempted - not at all.
