Your mind maybe playing tricks on you!

Nope, look again at my reply. I said "if". But, truth is it is not.

Dean's photo proves that the Coke can isn't triggering our brain to "see" red color. The Coke can is clearly still there in black and white, so why aren't we seeing it in red now? Because no red is there.

The fact is we see colors only because of the way our eyes were designed by God. We have things in our retinas called rods and cones. The retina sits at the back of the human eye. Your retinas are home to two types of photoreceptor cells: rods and cones. These specialized cells convert light into signals that are sent to the brain. This allows you to see, and to see color.

You have 20 times more rods than cones. Rods allow you to see in low light. Cones are 100% responsible for colour vision. Have you ever noticed how hard it is to see color in the dark? That’s because only the rods work in low light.

There are three types of cones: red, green and blue. Each type respond to different wavelengths of light. Long wavelengths stimulate red cones. Short wavelengths stimulate blue cones. Medium wavelengths stimulate green cones. When different combinations of cones are activated, you see other colors.

We are seeing the red in the Coke can because red is there, or, because long light wavelengths are reflected off it and we see what we call red, not because our brain is being "tricked".
