02.有彩色与无彩色

Chromatic Color and Achromatic Color

人们能够识别的色彩达到上千万种。色彩大致可以分为两类：黑白灰被称为无彩色；除了黑白灰以外的红、橙、黄、绿、蓝、靛、紫被称为有彩色。

我们把杂乱无章的有彩色分成六组：第一组含白的，第二组含黑的，第三组含黄的，第四组含红的，第五组含蓝的，第六组含绿的。

第一组含白的颜色给我们的第一印象是比较明亮。仔细观察能看出，有的颜色含红，有的颜色含绿，有的颜色含蓝，有的颜色含黄，有的颜色含灰。所以，明亮是这些颜色的共同属性。

第二组含黑的颜色给我们的第一印象是比较暗淡。同第一组颜色相似，有的颜色含红，有的颜色含绿，有的颜色含蓝，有的颜色含黄，有的颜色含白。所以，暗淡是这些颜色的共同属性。

第三组含黄的颜色给我们的第一印象是这些颜色都含黄，有些偏绿，有些偏蓝，有些偏黄，有些偏白，有些偏黑，但含黄是这些颜色的共同属性。

For humans,the recognizable colors amount to millions upon millions of kinds.In general,they can be divided into two categories.

Black,white and gray are called achromatic colors.The colors except the already mentioned,including red,orange,yellow,green,blue,indigo and purple are called chromatic colors.

Chromatic colors can be further divided into six groups:the first group is whitish,the second blackish,the third yellowish,the fourth reddish,the fifth bluish,the sixth greenish.

The first group leaves us the impression that these colors are bright.If we have a closer look,we can find that some colors contain red,some contain green,some contain blue,some contain yellow and some contain gray.Therefore,these colors share the same characteristic of brightness.

The second group leaves us the impression that they are kind of dull.Same as the first group,some colors contain red,some contain green,some contain blue,some contain yellow and some contain white.Therefore,they share the same characteristic of dimness.

The first impression on the third group is that these colors all contain yellow,some of which are greenish,some reddish,some whitish and some blackish.But they share the same characteristic of containing yellow.

第四组含红的颜色给我们的第一印象是这些颜色都含红，有些偏蓝，有些偏黄，有些偏黑，有些偏紫，但含红是这些颜色的共同属性。

第五组含蓝的颜色给我们的第一印象是这些颜色都含蓝，有些偏绿，有些偏黄，有些偏白，有些偏黑，但含蓝是这些颜色的共同属性。

第六组含绿的颜色给我们的第一印象是这些颜色都含绿，有些偏黄，有些偏蓝，有些偏白，有些偏黑，但含绿是这些颜色的共同属性。

通过这样的分组方式，上千万种颜色都可以归类到其中。

The first impression of the fourth group is that these colors all contain red,some of which are bluish,some yellowish,some whitish and some blackish.But these colors share the same characteristic of containing red.

The first impression of the fifth group is that these colors all contain blue,some of which are greenish,some reddish,some whitish and some blackish.But these colors share the same characteristic of containing blue.

The first impression of the sixth group is that these colors all contain green,some of which are yellowish,some bluish,some whitish and some blackish.But these colors share the same characteristic of containing green.

Through this grouping method,tens of millions of colors can be classified into them.
