Image color inversion effect

Quick answer：

The image color inversion effect is a technique used to change the colors of an image to their complementary colors. This means that each color in the original image is replaced by its opposite on the color wheel. For instance, red becomes cyan, green becomes magenta, blue becomes yellow, and black becomes white. This effect is often used for artistic purposes, to create a sense of contrast, or to simulate certain conditions, such as night vision or black and white photography.
