Most of the popular Hubble images are made by combining a red image, a green image, and a blue image.

combining light


Because of the way our eyes work, almost any color can be simulated by combining red, green, and blue light. All the colors combined make white light.

Many full-color Hubble images are combinations of three separate exposures ó one each taken in red, green, and blue light. When mixed together, these three colors of light can simulate almost any color of light that is visible to human eyes. Thatís how televisions, computer monitors, and video cameras recreate colors.
