This rainbow contains all the colors that you can see in the land below it—the yellow of the hills, the green of the leaves and grasses. It contains other colors as well. In fact, a rainbow contains all of the colors of visible light. Photographers use color theory to study different types of colors. The combining of colors in creative ways can add to the appeal and artistry of a photo.
::这个彩虹包含您在下面的陆地上看到的所有颜色—— 山的黄色, 叶子和草的绿色, 也包含其他颜色。 事实上, 彩虹包含可见光的所有颜色。 摄影师使用彩色理论来研究不同种类的颜色。 以创造性的方式结合颜色可以增加照片的吸引力和艺术性。The Colors We See
::我们看到的颜色The human eye can distinguish only red, green, and blue light. These three colors are called the primary colors of light. All other colors of light can be created by combining the primary colors. Mixing different colors of light is adding . Digital Cameras, computer monitors and televisions use this ability to create an amazing variety of colorful images. Look at the Venn diagram in Figure . Red and green light combine to form yellow light. Red and blue light combine to form magenta light, and blue and green light combine to form cyan light. Yellow, magenta, and cyan are called the secondary colors of light. Look at the center of the diagram, where all three primary colors of light combine. The result is white light. You can explore the colors of visible light and how they combine at this URL:
::人类的眼睛只能区分红色、 绿色和蓝色的光。 这三种颜色被称为光的主要颜色。 所有其他的光的颜色都可以通过混合主要颜色来创建。 混合不同的光的颜色正在添加 。 数字相机、 计算机显示器和电视使用这种能力来创建各种惊人的多彩图像。 查看图中的 Venn 图 。 红光和绿光组合成黄色的光。 红光和蓝光组合成黄紫色, 蓝光和绿光组合成青色光。 黄色、 红红色和青光组合成青光。 黄色、 紫色和青色被称作光的次要颜色 。 查看图表的中心, 所有的三种主要颜色组合在一起。 结果是白色的光。 您可以探索可见光的颜色, 以及它们如何在这个 URL 中组合在一起 :Red, green, and blue light can be combined in different ways to produce all of the colors of light.
::红、绿和蓝光可以以不同方式结合 产生光的所有颜色secondary colors are made by mixing equal amounts of primary colors. For example, magenta is made from mixing blue and red. Notice that the primary light colors are different than the red, yellow and blue we often learn about in art painting.
::二次颜色是混合等量初级颜色制成的。 例如, 紫红色是混合蓝色和红色制成的。 请注意, 初级光颜色不同于我们在艺术绘画中经常学到的红色、 黄色和蓝色 。
Complimentary Colors
::辅助颜色Complimnetary colors are found opposite each other on the color wheel.
::在色轮上 发现共性颜色对立
Analogous Colors
::模拟颜色Analogous colors are next to each other on the color wheel. Yellow and green are analogous colors.
::彩色轮上的类似颜色相邻。 黄色和绿色是相似的颜色 。
Value
::价值价值价值值Value is the lightness or darkness of a color. Pure color is called hue. Adding white to a color adds tint. Adding black to a color creates a shade . When grays are added the intensity of the color is changed
::值是颜色的亮度或暗暗。 纯色被称为 hue 。 将白色添加到颜色中会增加色调。 将黑色添加到颜色中会创造阴影。 当添加灰色时, 颜色的强度会发生变化 。The amount of white or black in a color is called the tone or value. In photography the amount of light available will affect your tones and .
::颜色中的白或黑的量称为音或值。 在摄影时, 可用的光量会影响您的音调和 。Temperature
::温度The purple, reds and blue-green colors on the color wheel are referred to as "cool" colors. Warm colors are the reds, oranges and yellows you would see in a sunset or sunrise. The word is to describe pictures that contain more colors from wither the warm side of the color wheel or the cool side.
::色轮上的紫色、 红色和蓝色绿色颜色被称为“ 酷” 颜色。 温暖的颜色是指日落或日出时会看到的红色、 橙色和黄色。 这个词用来描述从色轮的温暖面或凉爽面中淡化出更多颜色的图片 。
Pigments
::颜料Many objects have color because they contain pigments. A pigment is a substance that colors materials by reflecting light of certain wavelengths and absorbing light of other wavelengths. A very common pigment is the dark green pigment called chlorophyll, which is found in plants. Chlorophyll absorbs all but green wavelengths of visible light. Pigments are also found in many manufactured products. They are used to color paints, inks, and dyes. Just three pigments, called primary pigments, can be combined to produce all other colors. Mixing colors subtracts wavelengths because pigments absorb wavelengths. The primary colors of pigments are the same as the secondary colors of light: cyan, magenta, and yellow. When these three colors are mixed together in equal amounts, they make black-the absence of reflected light.
::许多物体都有颜色, 因为它们含有色素。 色素是一种物质, 它通过反映某些波长的光和吸收其他波长的光来颜色材料。 一种非常常见的色素是植物中发现的黑色绿色色素, 叫做叶绿素。 青霉素吸收了可见光的所有绿色波长。 颜料也在许多制成品中找到。 它们用于涂料、 油墨和染料的颜色。 只有三种色素, 叫做初级色素, 可以结合来产生所有其他颜色。 混合色素会减少波长, 因为色素吸收波长。 色素的主要颜色与次要的光色相同: 青色、 紫色和黄色。 当这三种颜色以等量混合在一起时, 它们使黑色成为反光的缺失 。Artists make paintings using a variety of pigments.
::艺术家用各种颜料做绘画。Q: A color printer needs just three colors of ink to print all of the colors that we can see. Which colors are they?
::问题:一个彩色打印机只需要三个墨水颜色来打印我们可以看到的所有颜色。它们是什么颜色?A: The three colors of ink in a color printer are the three primary pigment colors: cyan, magenta, and yellow. These three colors can be combined in different ratios to produce all other colors, so they are the only colors needed for full-color printing.
::A:彩色打印机中墨水的三种颜色是三种主要颜料颜色:青色、红红色和黄色。这三种颜色可以以不同比例组合,以产生所有其他颜色,因此它们是全色打印所需的唯一颜色。Summary

The human eye can distinguish only red, green, and blue light. These three colors are the primary colors of light. All other colors of light can be created by combining the primary colors. Secondary colors of light—cyan, yellow, and magenta—form when two primary colors combine equally.
::人类的眼睛只能区分红色、绿色和蓝色的光。 这三种颜色是光的主要颜色。 光的所有其他颜色都可以通过将主要颜色结合起来来创造。 光的次要颜色—— 青色、黄色和红红色—— 是两种主要颜色同等结合的次要颜色。 -
