Simultaneous Contrast

Simultaneous contrast is a visual phenomenon where the appearance of a color is affected by the colors surrounding it. For example, a gray square may look darker or lighter depending on whether it's placed on a dark or light background. This effect occurs because our eyes and brain interpret colors relative to their neighbors, creating an optical illusion that alters perceived brightness and hue. It’s a natural way our visual system enhances contrast and detail, but it also explains why colors can seem different depending on their context, influencing art, design, and visual perception.
