The process of reversing the color values of an image on an Android device results in a visual transformation where light areas become dark and vice versa. For example, a predominantly white image with black text would appear as a predominantly black image with white text after the color inversion is applied.
Altering an image’s colors can serve various purposes. It can improve accessibility for individuals with visual impairments by providing higher contrast. In specific design contexts, it allows for the creation of unique and eye-catching effects. Historically, similar techniques were employed in photographic processes to create negatives from positives.
