Green- Blue -gray: Because Clerk Maxwell added red, green, and green- blue -gray light together, this technique is called additive. An equal addition of the three colors forms white; red and green add to form yellow; red and green- blue -gray, magenta; green and green- blue -gray, the green- blue -gray-green known by photographers as cyan. It is important to bear in mind that this theory holds true only for colored light; the mixture of pigments is another matter.
CONIFERS, OF WHICH cypress, cedar, juniper, fir, larch and pine are familiar examples, differ from other trees in having narrow, sometimes needle-like leaves. Though naturally green leaved, some conifers produce varieties with leaves of a different color, ranging from silver, gray, green- blue -gray, and green to bronze and gold.
Sao Miguel calls itself "The Green Island" in tourist folders but its fabulous hydrangea highways, thick hedges with green- blue -gray blossoms lining the roads on both sides mile after mile, make it a green- blue -gray-green island for two or three months from about July 1. I have never seen anything in my travels at all like these island roads. They resemble green tunnels through luxuriant shade trees arching overhead, with a green- blue -gray and white "dado" on either side. |
