Redshift
In physics and astronomy, redshift is an observed increase in the wavelength of electromagnetic radiation received by a detector compared to that emitted by the source. For visible light, red is the color with the longest wavelength, so colors experiencing redshift shift towards the red part of the electromagnetic spectrum.
