Hmm…
I would assume then that the effect is somehow tied in with the fact that the light is diffused and relatively dim, since it’s simply a fact that the blues and greens are the colors that pop. Possibly there isn’t enough light to show up orange or red - effectively, everything is sort of in shadow?
And by contrast, as I write this, it’s very smoky where I am, and yes - the light is notably orange. And I’ve noticed before that when it’s like this, shadows have an obvious blue tint.
It’s the state of mind caused by simultaneously believing two (or more) things that conflict with each other.
