Abstract paintings take any shape or form preferred by the artist.
Acrylic paint is a water-based paint. Unlike watercolors, though, it is not easily washed off and is not soluble. The main benefit of acrylic paint is that it dries quickly, so painting is accomplished faster than with oil paints. Acrylics do have toxic components, so you should take care to avoid getting the paint in your (or anyone's) mouth or eyes accidentally.
Painting abstract art with acrylic paint can make the art durable in a similar manner to oil paints, and it gives the canvas brighter colors than watercolors.
Instructions
1. Draw the basic painting with a pencil. Though abstract art is based on inner vision and does not follow the same forms as classical or realistic art styles, sketching the basic picture makes it easier to paint. This gives lines and color regions for the painting.
2. Select colors. Acrylics come in a variety of pigments. Sometimes the perfect color for the project is not available, but blending paints creates new colors. When necessary, select a color that is close to the appropriate color and select another color to mix that will make the desired color. For example, if the preferred color is a dark red and a basic red is the only color available, get a black paint to mix with it and make a darker red.
3. Blend paint quickly. With acrylics, it is important to work fast, before the paint begins to dry, so blend as quickly as possible and start painting immediately.
4. Paint according to personal vision. Abstract art is about expression, personal vision and creativity. It does not need to look real or even identifiable.
