Paint in the various shapes, one color at a time. For instance, first paint in all the yellow shapes. Then all the orange shapes, then dark pink, light pink, etc.
Strive to create a balance. Have a variety of shapes and colors. The idea is that the different shapes and placement of colors will cause the viewer's eyes to bounce around the canvas.
Continue painting in these shapes until the white paper is mostly covered. These shapes will form the bottom layer of the composition. This first layer of shapes are painted next to each other, as opposed to on top of each other.
Now that the initial bottom layer is mostly covered, I start painting in smaller details on top of the shapes I already painting. This is called an additive process, or a layering process, because it involves adding layers to create the painting. This is one technique you can use to paint abstract art in acrylics.
In general, the new details I add are confined to the space of each particular shape. Thus each shape winds up being truly unique from all the other shapes.
I primarily paint circles, half-circles, dots, swirls, curls, raindrops, triangles, and lines.
The process of adding more layers of detail continues. As more details are added, they become smaller because I start placing details on top of details.
As mentioned earlier, the colors are chosen to create a sense of movement. I want the colors to pop off the canvas.
The repetitive designs start to form funky, sometimes intricate patterns. Creating a pattern is one element you can use to make an abstract work of art.
When I add details, I add them one color at a time. For instance, I'll add all the white details over the entire canvas, then I'll add all the red ones, and so on. This means I only have to squeeze out one color at a time. Because acrylics dry quickly, I try not to have more on my palette than I'll actually use!
