On this occasion, I accidentally selected the wrong blue from my paint drawer. It is easy to make this mistake when you have a good selection of blue paint tubes arranged in no particular order. Unfortunately, I did not notice my mistake until I had squeezed a small amount into my palette.
I did not want to waste the Indanthrene Blue I had picked up instead of Ultramarine Blue, so I painted the outlines for the Scottish seascape with the Indanthrene Blue to see where it would lead.
However, I was planning to continue my exploration with the limited colour palette I had previously chosen:
- Burnt Sienna
- Raw Sienna
- Ultramarine Blue
- Titanium White.
I had forgotten I had prepared two sheets of watercolour paper with different amounts of Yellow Ochre, a colour not included in that limited palette.
The first sheet of watercolour paper has only Yellow Ochre. The second sheet of watercolour paper is a light cream made with a small amount of Yellow Ochre mixed with lots of Titanium White.
