Mastering light in abstract art involves understanding how to use colour, value, and composition to create the illusion of light and depth in a non-representational work. Artists often use contrasting colours and values to create the illusion of light and shadow and may use techniques such as layering and texture to add depth and dimension to their work. Additionally, the use of movement, gesture and brushstrokes can also convey a sense of light and movement in an abstract composition.

The contrast in abstract art refers to the use of different elements, such as colour, shape, and texture, to create visual interest and contrast in a piece of art. One way to create contrast in abstract art is through the use of complementary colours, which are colours that are opposite each other on the colour wheel. Another way to create contrast is through the use of different textures, such as smooth and rough surfaces. Additionally, contrast can be created through the use of different shapes, such as organic and geometric shapes. The use of contrast in abstract art can help to create a sense of depth and movement in a piece, as well as to draw the viewer’s eye to specific areas of the artwork.
