I don't think the true color of anthra can be compared to outdoor photos. Yes, it changes in different lighting but the primary color is grey, not blue. Also, my anthra bbags are a lot more blue when I take a photo outdoors versus when I'm carrying them outdoors. Try to keep this info in mind so that when you do purchase anthra in any year you are not disappointed with the color IRL. The beauty is the chameleon effect in different light sources, that's why I have 3 anthra bbags!
I agree that it changes in different light, but both of my anthras are predominantly blue. Here are some indoor pics.
