When I went back to the battery yesterday I meant to take a ruler and correct my lines but I forgot it, so I just thought, hell, I’ll try to paint it from what I got transferred. So much for perfectionism. I strive for it but will never achieve it and I don’t worry about it too much. This will come out looking more like my interpretation of the battery than any photo realism.
The underpainting is in the complimentary colors of the ones I’ll paint on top of this. The battery is a warm gray because it’s concrete and weathered, so I painted it with cool grays first. The sky is a light tint of burnt umber because that’s a warm color. Now when I paint blue on top of this the blue will look brighter. The ground is a slightly darker tint of burnt umber because that’s what I saw under the grass. Sand.
If you want to paint with grays you need a good black to start. An equal amount of burnt umber and ultramarine blue make the best black. You’re mixing the darkest warm color paint with the darkest cool color and your black isn’t a dead black. Then you can mix white in for grays and make neutral grays or you can add any other color you want to and your grays will have some life. If you layer the grays warm then cool or cool to warm you’re also layering tints of complimentary colors which makes the grays look kind of pearly. The art viewer might not realize why the colors are pearly they just won’t get tired of looking at it as soon as they would if you only used flat grays. It makes the grays vibrate visually on a very subtle level that film can’t capture and computers can’t show you either.
Next step. I can do the sky at home. I’ll go back to mix colors for the grass next week. If I get my grays and greens mixed in plein air and start putting the colors in with my palette knife in plein air I’ll be able to see if it’s working out and might be able to work on it at home next week.
