Given the publicity that image has had there some reason to conclude that your colour vision may be abnormal.
What is clear is that you have great difficulty with any ideas that don't fit with your intuitions. Not only are you not able to see what a lot of people see you suggest that those that see it have defective vision and that those who don't agree with you "have axes to grind". Grow up!
