try turning up the brightness on your monitor maybe

and hold your eyes perfectly still while the weird color is displayed, and when the B&W image comes back

its weird, cause you see a colored photo, and you wonder if its a trick, so you move your eyes, and the color is gone.

BTW, the puffins head is mostly B&W no matter what, but the beak looks reddish/brownish
