Most of my abstract designs evolve over a white background giving the impression of having been done on white paper or maybe a white canvas. What happens if bold saturated colors are placed over a black background? I did just that and came up with some rather vibrant images.
One of the techniques used to create these designs in Procreate app is applying blending modes. The objects in the compositions are layered as if they were painted on clear glass or plastic then stacked one on top of the other to compose the final image. Blending modes allow for mixing or fragmenting the overlapped objects that are stacked. Part of one object might cause objects below it to change color where it overlaps. Sometimes the value (lightness or darkness) of the color will be affected as well. This is a great tool for making complex combinations of shapes.
