The opponent-process theory proposes that we perceive color in terms of paired opposites: red vs. green, blue vs. yellow, and black vs. white. The afterimage appearing blue instead of yellowish supports the idea that the opposing colors of blue and yellow were activated by the light bulb, creating the afterimage. The trichromatic theory suggests that we have three types of cone cells in our eyes that are sensitive to different wavelengths of light (red, green, and blue), which do not fully explain why the afterimage is blue instead of the original yellowish hue. The competitive and ancillary theories are not relevant to color vision.
