Canyon of Verdon

Has impact, though the tones are a little close to one another for my liking; try pthalo blue and raw sienna for a "parched" green, ultramarine and cad yellow for a dullish green, pthalo blue and lemon yellow for a sharp strong green, putting your strongest and greenest greens in the foreground. Add a small quantity of red (burnt sienna, permanent rose, even cad red) to greens to shadow, darken and dull them. Have a go with cobalt blue and lemon yellow, cerulean and lemon yellow for a very bright colour, or produce what I'd call an "interesting" green (ie, you wouldn't want to paint the whole picture with it, but it'll stand out where you apply it!) from Naples Yellow and Cobalt, maybe plus a touch of Yellow Ochre. Take a big sheet of paper and try all these mixes and more out, making sure you label them. Betes noires need to be taken on and decisively clobbered.

Thanks Robert, I have to work through those combinations
