Today I came across five pieces of paper that I was going to make into a collection of abstract paintings.

Now it was time to start putting colour into the various shapes. I started on the left side and painted the long rectangle with pure alizarin crimson.
Next, I made an orange of cadmium red and cadmium yellow and painted the large shape on the top right corner.
While that section was drying I mixed aureolin with Antwerp blue and painted in the small shape on the lower right side.
Using pure cadmium yellow I filled in the shape between the red bar and the orange shape.

Once the paint was dry, I washed a layer of cadmium red over the shape on the left side to darken it slightly.
