What are the differences between red and blue 3D technology?

Red and blue 3D technology, also known as anaglyph 3D, use different color filters to create the illusion of depth. Red 3D uses a red filter for the left eye and cyan filter for the right eye, while blue 3D uses a blue filter for the left eye and red filter for the right eye. This results in slightly different color perception and can affect the overall viewing experience.
