though i probably don't have a deep understanding of these things, i think you are right. i made some screenshots on: http://www.romanhaefeli.net/gem/
from the screenshots, it's not obvious that the problem is like that, because the colours as they are don't look unlikely, they look like they are just lit with yellowish light (fluor or neon), or that the chroma balance is off. With histograms, evidence could be a lot more telling that my semi-trained eyes, but even that could depend on the quality of the camera sensors. So really, the only way to know is to either make the reasoning that I made and check that it makes sense, or experimentally verify by using the same camera in different circumstances (e.g. in MS-Windows).
