|Phthalos tend to be potent, staining colors. Almost violent. The addition of the Indian Yellow toned them down and brought out softer, green tones. Very aquatic.|
Many Moons ago I painted a sea turtle from a photo ref on Wetcanvas. It was the first successful watercolor I ever painted and no one was more surprised than me that it turned out well. At the time I had only 10 paint colors, a small set of Robert Simmons synthetic sable brushes and no idea what I was doing. I managed to mix my own sea color, a lovely shade of turquoise, from D/R Phthalo blue, Phthalo green and Indian yellow. I've got a request to recreate that same painting for a friend. The first sold a few years ago. Fortunately I have the same paints in the same brand (very important because colors can vary from mfg. to mfg.). Today I played with various mixtures to find the right shade and I think I've managed to do just that. I wish I could show a side-by-side comparison with the sample swatch but the image of the original painting appears too blue on screen for some reason. I'm just glad I remembered the 'recipe'.
