As I said, the effect doesn't happen when you're looking at images, you need to be looking at the real piece.
Anyway, reddy-green is brown, and bluey-yellow is green (when mixing pigment).
Red and green are quite distant wavelengtht from each other, while blue and yellow do merge over greens.
I'm sure the phenomenon you are discussing here is the shifting of perception between two dichotomous stimuli - certainly with the reddy-green thing. The shift itself is a conscious mental phenomenon - you're aware of it, and I think that adds a certain piquancy, something extra and slightly delightful to the experience of looking at it.
I'm not so sure what you mean with your bluey-yellows - because bluey-yellows are the colours I seem to be most attracted to - the effects of silver chloride in glass, and perhaps I look at it so much, just enjoying it, I don't consider whether it is blue or yellow or green, I mostly love that I simply don't know, I don't need
to give it a name, I love the experience.
And loads of other folk call green what I'd call blue, or blue what I'd call green.
that distinction is purely the individual's choice of label to give it.
