Here are three new abstract designs. All were created in Procreate app for iPad. I used the same basic technique for all three designs. Starting with a black pen tool, I set the overall design down on one layer. I made this the “reference” layer which allowed me to just drop solid colors into any open area in the reference design. For example, the illustration below shows the “filling-in” of the first two colors.
I used six colors for the completed design, each color on a separate layer. Then I added various textures to the individual color layers. I added five rectangles onto a top layer which show through transparently in a blue-green tone.
Here is the finished design.
The second design was created in the same way using a reference layer and filling in with six colors on separate layers. Textures were added to the individual colors. The main difference with this composition is that I used an airbrush tool to break up the original line design (reference) with black and white. This gives it a metallic appearance.
The last composition started out in the same way as the first two; reference line design and color fill-ins. Eight color layers were used. No textures were added to the individual colors. White was used as the reference line color. A top layer was added with three light blue polygons used transparently to add color and complexity. An airbrush tool was then used to add color toning to a couple of the color layers. Finally, I brought the completed image into iColorama app and added the surface texture over the whole design.
