Excavator and vehicle are painted using negative technique. That's why I wet the whole sheet first and work on the first layer. For the background behind the excavator, cobalt turquoise and cobalt coelin and a little cadmium yellow are used. For the vehicle I use Indian yellow and cadmium yellow plus grey-violet for the floor. I seldom use fresh grey, but the colour remainings of my palette - it usually looks" more natural" than fresh grey colours.
Now I'm going to focus on the background. I wet everything except the machines and put a mixture of Delft blue, hematite black, quinacridone gold hue, saturn red and permanent red orange on the wet paper. I vary the amount of each color, so that at the end you will achieve beautiful violet-blue-brown gradients. Thus, you can paint stone without actually having to paint stones. While this mix is still wet, I add cobalt turquoise - it immediately looks noble and fresh. Where the shovel "pours out" the material, Indian yellow and quinacridone gold hue are used.
