Only 50 shades of grey?

What a poor experience – only 50 shades of grey (or Grey ;))… is that’s all?!

No-no, don't worry! Life is much better - actually, our eyes can easily distinguish at least 500 shades of grey!

As well as we can detect up to 10 million different colors with our eyes and easily turn this rainbow into extremely pleasurable firework of senses

                        

      I definitely choose a colorful life experiences!
