No, I dont think we are perceiving a shift in wavelength either.
A shift in wavelength means a shift in colour.
But I have now come to the conclusion that Grey is not a colour?
Black, is not classed as a colour.
And I dont think White is either?
Is'nt Grey, Black with a percentage of White in it or v-versa?
(Pedantic arguement. Hehe)

NASA's cheated us. Therefore, to my mind, A and B show slight differences in amplitude.
B must have a tad more Black in it than A, due to the shadow
cast across it by the green pole? Or am I wrong?
