I guess maybe because we are happy ...:) lame answers!! I read a book that when our emotions shows something like happy or sad or mad, our minds especially the minds that control our eyes reflect our emotions through color. That's common. Brain are complicated and emotions give our brain certain order by showing a little bit of color that reflect our moods. When we are sad, we might see thing a little bit gray or black and white. But when we are happy, we like seeing thing in much bright colour.

when i was happy, i don't think that what i see turn t "pink" color well, perhaps when someone happy, he will able to see world better than before. every single mistake that exist not being big problem for him. it will be in the contrary if this person being unhappy. evrerything will become wrong and worst in his opinion no matter how. i think its explain about pink in happiness and black in unhappiness
