Thick paint used to create ridges on canvas creates an 'actual texture', which is physical and can be felt, adding realism to the painting.
Understanding Texture in Art
When thick paint is used to create ridges on canvas, the type of texture that is created is called actual texture. This is a tangible element that adds to the expressiveness of a painting and can draw attention to specific areas within it. Actual texture engages not only the sense of sight but also the sense of touch. Artists such as Rembrandt van Rijn and Vincent van Gogh were known for their use of actual texture, such as impasto, to enhance the realism and sensory experience of their artworks. This contrasts with visual texture, which only creates the illusion of texture and remains smooth to the touch.
