Visual characteristics refer to the observable traits of an object or scene that can be perceived through sight. These traits include color, shape, size, texture, and patterns. For example, the color of a flower can indicate its species, while the shape of a leaf can help identify a particular tree. In addition to these basic traits, visual characteristics can also encompass aspects like brightness, contrast, and clarity. These elements play a crucial role in how we interpret images and objects. For instance, the brightness of a painting can evoke different emotions, while the contrast between colors can enhance visual appeal.
