Texture can be the line quality of a design. With texture, lines and surfaces can be described as smooth and rough.
Texture is very important in the perception of surface quality which creates sensations and experiences. Physical Texture is the texture you can actually feel with your hand, while visual Texture is the illusion of physical texture, created with the materials used in the art piece.
Well it all depends on how you think of art tbh . for me it would be like painting and designs to make and the color wheel I would think of. so it really depends on how you feel bout art.
