negative and positive color images

Quick answer：

Negative and positive color images refer to the use of color in photography or visual art to convey different emotional tones. Negative color images often use darker, more subdued hues to evoke feelings of sadness, melancholy, or unease. Positive color images, on the other hand, use brighter, more vibrant colors to evoke happiness, optimism, or excitement. These techniques are used to influence the viewer's emotional response to the image.
