1972 shades of blue

I know a guy that is only able to see the color blue, he can tell apart 1972 shades of blue, ever since he was a child he started naming all this shades, blue tea cup, blue car in the afternoon, etc., he hasn´t been able to get a well paid job because of this peculiar characteristic. He says that he will get the perfect job once his dead; He thinks he will be allowed to paint the sky. So in order to fulfill his destiny and do what he was born to do, he decided to kill himself.
