Valentine’s Day science: why do we see roses as having red color?

Coma Niddy is getting ready for Valentine’s Day, a day where 100 million roses will be given as presents. He explains why the green of the flowers is less brighter than the red during the day and why the green of the flower is brighter than the red during the night. This is because of the Purkinje effect.

All this depends on how our eyes process the light because we have two different modes for seeing: photopic vision (well lit – cone cells, for red, green , blue, most sensitive to yellow light) ans scotopic vision (low light – rod cells for dimmer or brighter objects in the night, can’t see color, most sensitive to green and blue light).

Now, because of the Purkinje effect you know that on Valentine’s Day you can offer roses with no bright lights around and she can still that those are roses. Share love people!
