A background color is the color that fills the background of an image, webpage, document, or any other graphical element. It serves as the backdrop against which other elements, such as text, images, or graphics, are displayed. Background colors are commonly used to enhance the visual appearance of content, provide contrast, and contribute to the overall design aesthetic.
In 3D rendering, the background color refers to the color that appears in the background of a rendered image or scene. It is the color that fills the areas of the image where there is no geometry or where the scene extends beyond the visible objects. The background color can have a significant impact on the overall look and feel of the rendered scene.
