The tree’s visual texture is represented here in this image.
Meaning the way a surface feels or is perceived to feel. Texture can be added to attract or repel interest to an element, depending on the pleasantness of the texture.[5]

Types of texture
Tactile texture is the actual three-dimension feel of a surface that can be touched. Painter can use impasto to build peaks and create texture.[5]
Visual texture is the illusion of the surfaces peaks and valleys, like the tree pictured. Any texture shown in a photo is a visual texture, meaning the paper is smooth no matter how rough the image perceives it to be.[5]
Most textures have a natural touch but still seem to repeat a motif in some way. Regularly repeating a motif will result in a texture appearing as a pattern.[5]
