I did capture an image with green present, but only because it was right next to pink:  The pink caused the green to appear to be next to it in an optical illusion.

Yes. Look at this, for example: [ Invalid Attachment ] Then cover all the pink parts and compare the greys.

In this one I have turned pink into green: [ Invalid Attachment ]


The effect (purple triangle inside of the green) is much less apparent, however; you have to enlarge the picture and/or look at it for a while, to see it.
I have tried with a lot of different colours and the more apparent effect is given just with pink dots.
