The thing one notices right off the bat is Corot’s use of other supporting colors: Ochers, Olive Greens, Silver Grays, and Deep Blackish Hunter Green tones that are surrounding and flourishing in the overall mixture. And usually, there is a lone figure, a peasant or a passer-by, an edge of a boat, or a swatch of brilliant Rose Madder or Magenta popping out to grip our eye to a fixed point of color heraldry. A grace note is given amidst the sea of green.
.... but it is an actual conjuring by the use of colors that are just plain “not green” that makes Corot’s green so effective.... Green is communicated in the midst of green hardly being used. Corot’s green is more like Corot’s Silvery Misty Verdant Grey.... There’s probably no accident that camouflage on military vehicles employed Corot’s approach. Olive Drab Green with a greyish tint hides things in the foliage just fine, because this is more to the true color of the stuff it’s trying to blend into.
....When we look at life there is a kind of shadow effect. Colors are not always what they may appear to be in our minds. The actual visual effects of color have their own hue, tone, shade, and quality of brilliance. Green is such a deceptive color in the repertoire of vision.
