According to researchers, the 'fill in' effect makes only a small contribution to how we perceive colors in an image. The study also provides new evidence that color processing cells play a vital role in color perception.
While only 1 in 25 people has synesthesia, a new study reports intuitions about 'sound colors' are shared by a greater percentage of people. Sound color perception is mainly driven by the vowels in language.
Visual neurons selectively respond to color and shape along a continuum. While some neurons are only activated by either a specific color or shape, others are responsive to color and shape simultaneously. The findings contradict previous beliefs about how visual processing works.
