The opponent-process theory of color vision is commonly used to explain the after-image phenomenon. This theory suggests that our visual system processes colors in opposing pairs (red-green, blue-yellow, black-white), and when we stare at a colored object for an extended period of time, the visual receptors become fatigued, leading to a temporary after-image in the opposing color.
The afterimage phenomenon is best explained by the opponent-process theory of color vision. This theory posits that color perception is controlled by opposing retinal processes, specifically the interplay between pairs of colors: red-green, blue-yellow, and black-white. When one color is overstimulated, as in staring at a bright image, the corresponding opponent color remains after the stimulus is removed, creating the afterimage effect. This explains why we see a complementary color when we look away from a bright source.

The most widely accepted theory for the Moon's origin is the Giant Impact Hypothesis. This theory suggests that a Mars-sized object collided with a young Earth, ejecting debris that eventually coalesced to form the Moon. This theory is supported by similarities in isotopic compositions between Earth and the Moon.
The afterimage phenomenon occurs when a visual stimulus continues to appear in one's vision after the stimulus has been removed. This effect is most commonly experienced with bright or contrasting images, where staring at a particular color can lead to seeing its complementary color once the gaze shifts away. This happens due to the temporary adaptation of photoreceptors in the retina, which become desensitized to the original stimulus. Afterimages can be both positive (retaining the original color) or negative (showing the complementary color).
The opponent-process theory is the most widely accepted explanation for the afterimage phenomenon. This theory suggests that color vision is based on opposing responses generated by blue-yellow, red-green, and black-white channels in the visual system. When staring at a colored image for a prolonged period, the system becomes fatigued, leading to the appearance of an afterimage in complementary colors.

The opponent-process theory is commonly used to explain afterimages. This theory suggests that the visual system has pairs of color channels that perceive opposite colors (e.g., red-green, blue-yellow), and when one is fatigued, the opposing color is perceived as an afterimage.
The wave theory of light best explains interference phenomena, where light is considered to propagate as a wave. This theory posits that when two waves overlap, they can either reinforce (constructive interference) or cancel out (destructive interference) each other depending on their relative phases. This accounts for the patterns observed in interference experiments.
