Scientists describe differences in the colors of near-death visions: tunnels are black-and-white, spaces are colorful
Researchers from the University of Haifa analyzed the memories of 50 people who had survived near-death experiences. Tunnels were more often remembered without vivid colors, while wide spaces were remembered in color. The authors note the study's limitations and do not consider it an explanation of the nature of such experiences.
