Color is one of the most obvious and pervasive qualities of human visual perception. While it is possible to recognize objects and perform most visual tasks without chromatic information, color adds another dimension to perception. After watching a black and white film on television, one is often struck by the richness of perception when a colored image is restored. Similarly, a black and white photograph of a natural scene, seldom conveys the full beauty of the original.
色彩是人类视觉感知中最明显、最普遍的信息特点之一。虽然没有颜色信息也可以识别物体和执行大多数视觉任务，色彩给感知增加了另一个维度。看完电视上的黑白片后， 当某些图像恢复为彩色图像时，人们常常被感知的丰富性所震惊。同样，一张黑白的自然风光照片，很少能传达出全部的原始的美丽。
Color plays an important role in many different areas of our lives. Important messages are often conveyed by colored signals - red usually meaning danger or stop and green, go or all clear. Color coding is used extensively in industry, e.g. electrical wiring, electronic components, pipelines, gas cylinders, chemical containers etc. In education, color is a useful tool for reinforcing concepts and many learning schemes adopt a system of color coding.
在我们生活的许多不同领域，颜色都起着重要的作用。 颜色信号传递出重要信息 - 红色通常意味着 危险 或 停止 ,而绿色意味着 开始 或 明了. 彩色编码广泛应用于工业中，如电线、电子元件、管道、气瓶、化工容器等。 在教育系统中，颜色是增强概念的有用工具，许多学习方案采用颜色编码系统。
Over the past decade the use of computers has increased dramatically. Modern computers are capable of displaying many thousands of colors on the screen simultaneously and colors are often used to code or highlight different classes of information on the screen.
在过去的十年里，计算机的使用急剧增加。现代计算机能够同时在屏幕上显示成千上万种颜色，颜色经常用来在屏幕上编码或显示不同种类的信息。
The value of color in advertising is now well established - different combinations of colors being used according to the nature of the product or service being advertised. Companies use certain color combinations to create a corporate identity and over time, the colors alone often become sufficient to identify the company.
颜色在广告中的价值现在已经确立——根据广告产品或服务的性质使用不同的颜色组合。公司通过某种颜色组合来塑造企业形象，随着时间的推移，颜色往往足以识别公司。
