Color photography developed rapidly after World War II, both as color positive (slides) and color negatives (prints). In accelerated aging tests, published in 2000, color positive photographs were found to retain color accuracy indefinitely, provided they were stored with adequate environment controls and were not projected or exposed to light. Color negative photographs, on the other hand, were found to lose color accuracy by fading or color alteration fairly rapidly. At that time Fujicolor was found to be the most stable of the color negative brands. Kodacolor had poor color retention. Polaroid color prints were probably the least color stable. Improvements over the past ten years make most brands about equal in quality today.
