An Optical Answer

Here is the answer for that other post... quite an interesting thing right?

Our eyes often deceive us. In this case, it was merely the perceived shadow on the blocks that made it look like different colours. Merely. It doesn't take much for us to be deceived. Where then can we rely on truth?

Sometimes, what we see is what we get. But most times, what we see is hardly anything to go by. Because we are all flawed. We are all blind to some extent.
