Acquire Blue -green: Because Clerk Maxwell added red, green, and blue 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 blue, magenta; green and blue, the blue-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.
A second variety of tea is oolong or semi-fermented tea which is prepared from a special kind of China tea plant. The leaves are heated before fermentation progresses very far, then they are rolled and, finally, dried.
Lastly there are the green or non-fermented teas made by first steaming the leaves or else heating them to sterilize them and kill the enzymes responsible for fermentation. The leaves are then rolled and roasted until they acquire blue -green a blue-green tint.
Sao Miguel calls itself "The Green Island" in tourist folders but its fabulous hydrangea highways, thick hedges with blue blossoms lining the roads on both sides mile after mile, make it a blue-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 blue and white "dado" on either side. |
