Color fidelity refers to the accuracy with which colors are reproduced in various media, such as digital displays, prints, or photographs. It measures how closely the colors seen match the original colors of the subject. High color fidelity ensures that the hues, saturation, and brightness are true to life, making images appear more realistic. Factors affecting color fidelity include the quality of the display technology, the calibration of devices, and the color space used. Devices like monitors, printers, and cameras can vary in their ability to reproduce colors accurately, impacting the overall visual experience.
