Appearance design refers to the aesthetic and practical design of the shape, pattern or combination of the product
as well as the combination of color, shape and pattern.
New designs for industrial applications.
The shape and pattern of the product or their combination and the combination of color and shape and pattern constitute the three elements of product design: shape, pattern and color
The pattern of the product should be fixed, Visible, rather than being occasional or needing to be seen under specific conditions.
The color of a product cannot independently form a design (picture below) unless the color change itself forms a pattern.
