I suspect this happens because the cones (which detect colour and are more sensitive than rods) are concentrated in the middle of the retina, and the colour leaves an after-image on the retina that appears on the black and white image for a moment.

And the color image persists...

Try looking away for about 15 seconds and then back.

My brain, when I look at the dot on the black and white picture, wanted to paint in the color for quite a while afterward...
