Ways to Create Colors in a Photograph
There are two ways to create colors in a photograph.One method called additive,starts with three basic colors and adds them together to produce some other color. The second method,called subtractive,starts with white light(a mixture of all colors in the spectrum)and,by taking away some or all other colors,leaves the one desired.
In the additive method,separate colored lights combine to produce various other colors.The three additive primary colors are green,red and blue(each providing about one-third of the wavelengths in the total spectrum).Mixed in varying proportions,they can produce all colors.Green and red light mix to produce yellow,red and blue light mix to produce magenta(a purplish pink);green and blue mix to produce cyan(a bluish green).When equal parts of all three of these primary-colored beams of light overlap（重叠）,the mixture appears white to the eye.
In the subtractive process colors are produced when dye（染料）absorbs some wavelengths and so passes on only part of the spectrum.The subtractive primaries are cyan,magenta and yellow; these primaries or dyes absorb red,green and blue wavelengths respectively,thus subtracting them from white light. These dye colors are the complementary colors to the three additive primaries of red,green and blue.Properly combined,the subtractive primaries can absorb all colors of light, producing black.But,mixed in varying proportions,they too can produce any color in the spectrum.
Whether a particular color is obtained by adding colored lights together or by subtracting some light from the total spectrum,the result looks the same to the eye.The additive process was employed for early color photography. But the subtractive method,while requiring complex chemical techniques,has turned out to be more practical and is the basis of all modern color films.

参考答案
参考解析
解析：这是一道理解主旨的题。第一段第一句明确提出，照片中的颜色是通过加色法和减色法两种方式形成的。之后二、三段分别详细介绍了两种方式的具体情况。A、B、D选项均不是文章主旨。
第二段最后一句话提到当等比例的三原色重叠时，形成白色。因此B选项是正确的。
这是一道关于减色法过程的细节题。根据第三段第二句话可知，减色法中的三原色分别是蓝绿色、紫红色、黄色；它们分别从白色中吸取红色、绿色、蓝色的光波。故可得出蓝绿色吸收的是红色的光波。
根据文章内容可知，加色法的三原色分别为红、绿、蓝，减色法的三原色分别是蓝绿色、紫红色、黄色。没有黑色和白色。
根据最后一段可知，通过加色法和减色法所获的特定颜色用肉眼来看效果是一样的。加色法用于早期彩色照片的处理，而减色法虽然需要复杂的化学工艺，却被证实是更为实用的方法，所以它成为了现代彩色胶片的基础。由此可知相对于加色法，减色法更为有效。

Verity Allen's New Show on Colors1 Different colors can affect us in many different ways;that's according to Verity Allen.In her new se- ries'Color me Healthy',Verity looks at the ways that colors can influence how hard we work and thechoices we make.They can even change our emotions and even influence how healthy we arc.2 "Have you ever noticed how people always use the same colors for the same things?" says Verity."Ourtoothpaste is always white or blue or maybe red.It'g never green.Why not?For some reason we think that blue and white is clean,while we think of green products as being a bit disgusting. It's the same for businesses.We respect a company which writes its name in blue or black,but we don't respect one that uses pink or orange.People who design new products can use these ideas to influence what we buy."3 During this four-pait series,Verity studies eight different colors,two colors in each program.Shemeets people who work in all teipects of the color industry,from people who design food packets to people who name the colors of lipsticks.4 Some of the people she meets clearly have very little scientific knowledge to support their ideas,such as the American"Color Doctor"who believes that serious diseases can be cured by,he use of colored lights. However,she also interviews real scientists who are studying the effects of green and red lights on mice,withsome surprising results.5 Overall,it's an interesting show,and anyone who watches it will probably find out something new.But because Verity goes out of her way to be polite to everyone she meets on the series,it's up to the viewers to make their own decisions about how much they should believe.Paragraph 5_______________A:The Same Colors for the Same ThingsB:Scientists' Surprising ResultsC:Verity's View on the Influence of ColorsD:Knowledge of the Interviewees on ColorsE:Studies in Verity's SeriesF:The Author 's Opinion About Verity's Shows
