Why Black and White Photos Evoke Better Memories

Reason:

You gotta squint hard at a black and white photo without much context, which forces you to use your imagination and add color to your past (monochrome photo) memories.

As a consequence, the “disfluency” of the image (the fact that a high contrast, sometimes blurry or out of focus photo) isn’t clear is precisely what makes the photograph or memory more memorable.
