BCDS—商用色彩设计的系统
BCDS- Business Colour Design System
1、 BCDS的理论来源
1. The Theoretical Source of BCDS
公元1773年，中国古代学者和发明家博明在他的著作《西斋偶得》中，讲到：“五色相宣之理，以相反而相成，如白之与黑，朱之与绿，黄之与蓝，乃天地间自然之对，待深则俱深，浅则俱浅，相杂而间色生矣。”博明认为，在颜色中存在三个相反的“自然之对”，即白与黑、红与绿、黄与蓝。每一对颜色之间都存在着比对关系，可以相互衬托，一方色重，另一方看上去也重；一方色浅，另一方显得也浅，把它们掺在一起，就产生了别的颜色。
In 1773 A.D., Bo Ming, an ancient Chinese scholar and inventor, said in his works Random Thoughts in West Study that “all kinds of colors set off and reflect, different colors rely on each other that is identical, for example, white and black, red and green, yellow and blue, is a kind of correspondence between Heaven and Earth, all darkness becomes darkness and all light colors turn into light color, in which mix in colors generates a color.” Bo Ming believed that in terms of color there are three opposite “natural correspondence”, i.e., white and black, red and green, yellow and blue. There is a comparison relationship amid a pair of colors that may set off each other, one color becomes darker along with another color; one color becomes lighter along with another color, mixed together that generates another color.

商用色彩设计体系理论诞生在21世纪初，以中国北京领先空间商用色彩研究中心吕光为核心团队的中外当代色彩研究者、设计者和教育者们，提出并创建了完全基于人类视觉生理的补色机制为主的色相关系的色彩设计系统，建立了色彩设计应用体系。
Business color design system theory was born at the beginning of 21th century. As the core team of Beijing Leading Business Color Space Research Centre, LvGuang and his fellow researchers, designers and educators of modern color from both at home and abroad, put forward and set up a color design system of hue relationship entirely based upon the color complementary mechanism of human visual physiology and established a color design application system.
BCDS是为了全面解决颜色量化设计和色彩教育学习方法的问题，它采用自然颜色和人文色彩交叉式研究与综合教育的形式，把色彩价值体现作为色彩教育的根本，实现和完成了色彩设计从感性到理性的飞越。我们运用BCDS颜色空间来设计和诠释色彩现象，以BCDS作为颜色设计平台，运用BCDS自然规律研究颜色设计方法，将设计中的“色彩感觉”转化为“量化应用”；以传授科学的色彩设计方法为目的，以色彩训练为手段，全面提高设计师对色彩的综合掌控能力。商用色彩：色彩价值体现，即物理颜色和心理颜色的有价值交换。
BCDS has comprehensively solved the problem of color quantization design and color education study method which adopted natural color and humanistic color intersection research as well as form of comprehensive education, taking color value as the root of color education, realizing and completing the flyby of color design from the perceptual to the rational. We use BCDS color space to design and explain the color phenomenon, taking BCDS as a color design platform, using BCDS’s natural law to study color design method, turning chromatic sensation into quantitative application in design; passing on scientific color design method as an end and color training as a means for which comprehensively improve a comprehensive control ability of designers to color. The business color: color value refers to the valuable exchange of physical color and psychological color.
2.BCDS基准色的表述：
2.The Representation of the BDCS Reference Color
BCDS基准色的概念是，只要从色相上判断或表述出一个颜色，就必须建立起色相的评价范围。从可见光波在380~780nm 波段，BCDS选择有代表性的十个基准色作为评价颜色色相的范围，它们分别是：Red=红(R)630-750nm、Orange=橙(O)595-630nm、Yellow=黄(Y)580-590nm、Kelly=薇(K)560-580nm、Green=绿(G)500-560nm、Turquoise=青(T)480-500nm、Blue=蓝(B)435-480nm、Purple=紫(P)400-435nm、White(W)＝白、Black(B)＝黑，两个无彩基准色与其他颜色组成颜色的空间范围。 
BCDS` concept of reference color means that as long as the judgment is made from hue or express a color, an evaluation scope must be set up. From visible light wave at 380~789nm wave band, BCDS choose ten typical reference color as a scope of evaluation of color hue, they respectively are: Red=(R)630-750nm, Orange=(O)595-630nm, Yellow=(Y)580-590nm, Kelly=(K)560-580nm, Green=(G)500-560nm, Turquoise=(T)480-500nm, Blue=(B)435-480nm, Purple=(P)400-435nm, White(W)＝, Black(B)＝, two achromatic reference colors and other colors together form the scope of the color space.

3.BCDS色相圆环的表述：
3. The Representation of BCDS Hue Circle
BCDS色相圆环是一个完全的生理色相环，它依照我们的视觉习惯按顺时针方向排列。每两个基准色之间划分为100阶，跨10取1，共有80个色相（Hue），基准色一律以100表述为：R100、O100、Y100、K100、G100、T100、B100、P100，其余非基准色的数值只能是两个相邻基准色之和等于100，即是：O+Y、Y+K、K+G、G+T、T+B、B+P、P+R、R+O=100；表述方法按顺时针方向，以基准色排列先后顺序表述，如：B40P60、B50P50、B60P40等。
BCDS hue circle is a complete physiological hue circle that goes clockwise direction according to our visual habits. Every two reference colorsare divided into 100 levels,taking 1 across 10,totally 80 hue, the reference hue is to be expressed all by 100: R100, O100, Y100, K100, G100, T100, B100, P100, while other non-reference colors’ numerical value can only be the sum of the adjacent reference color that equals 100,i.e. O+Y, Y+K, K+G, G+T, T+B, B+P, P+R, R+O=100; the expression method is by clockwise direction, to express according to reference color arrangement in sequential order like B40P60, B50P50, B60P40 and so on.

4.BCDS颜色的三角表述：
4. The Triangle Presentation of the BCDS Color
BCDS采用b（black）、w（white）、c（chroma）小写符号分别表示颜色的黑度、白度和彩度属性（采用小写符号是为了与色相大写符号相区别）。并规定在空间中所有颜色的含量都是b+w+c=100，即任意颜色都包含有黑度、白度和彩度的成分，它们共同组成该颜色的100%含量。
BCDS adopt lower case symbols b(black) ,w(white) , c (chroma) to show colors’blackness, whiteness and chroma property(adopting lower case symbols is to distinguish from the capital symbol of hue) and stipulates that the content of all color in space being b+w+c=100, i.e. any color contains the element of blackness、whiteness and chroma, all of which together form 100% content of the color.
在BCDS空间中，颜色的黑度、白度、彩度分别表述为：
黑度：b= 0、1、2、3、4、5、6、7、8、9、10、11……100,共100级
白度：w= 0、1、2、3、4、5、6、7、8、9、10、11……100,共100级
彩度：C= 0、1、2、3、4、5、6、7、8、9、10、11……100,共100级

In the BCDS space, blackness, whitening and chroma are respectively shown as follows:
blackness: b=0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11…a total of 100 levels
whiteness: w=0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11…a total of 100 levels
chroma: C= 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11…a total of 100 levels

5.BCDS颜色的编码
5. The Coding of BCDS Color
将颜色的色相编码和色位编码组合起来就是一个完整的BCDS颜色编码了。例如：
Combining hue coding with color coding is a complete BCDS color coding, for example:

需要注意的是，在编码的时候留心色相的总和与色位（色貌）的总和要分别等于100。在这里彩度的编码不用记录，因为只需要表示出黑度和白度，彩度的数值自然就可以得出。黑白灰等无彩色的表述为：N（No）代表没有彩色，黑色N b100w00、白色N b00w100、中灰色N b50w50等。
Attention, the sum of hue and color (color appearance) shall respectively be 100 at the time of encoding. Here the coding of chroma is not to be recorded, because it only needs to show blackness and whiteness the chroma value will be calculated naturally. The color black, white and grey etc with neutral color are expressed as: N (No) signifies neutral color, black N b100w00, white N b00w100, neutral grey N b50w50 and so on.
6、BCDS色彩的空间表述
6. The Space Representation of BCDS Color
在BCDS中，八个有彩基准色和两个无彩基准色共同构成了衡量所有颜色的色彩空间。完整的BCDS空间犹如两个倒扣的圆锥体，最大直径的地方是彩度最高点（把所有彩度最高点连接起来就是BCDS色相环），上下两个顶点分别为白度最高点和黑度最高点。所有可见颜色都可以在BCDS空间中找到自己的位置，也就是色位。

In BCDS, eight chromatic reference colors and two achromatic reference colors commonly constitute a color space that measures all colors. A complete BCDS space is just like two overturnedcones, where the maximum diameter is thehighest point of chroma (linking up all the chroma high points together is BCDS color circle), up and down vertices respectively are the whiteness highest point and the blackness highest point. All the visible colors can find their own location in BCDS space, i.e. color location.

7.BCDS颜色的三角区域表述：
7. The Triangle Area Representation of BCDS Color
在BCDS色位区域中，我们将八个基准色按照设计要求，在色位空间中进行七大设计应用区域组合，为设计色彩提供了基础的心理色彩对应应用平台。

In BCDS color location area, we combine eight reference colors in seven big design application areas in color space according to design requirements, providing a basic psychological color corresponding application platform for color design.

8、BCDS心理颜色快速指导应用
8. The Quick Guidance Application of the BCDS Psychological Color
颜色心理与颜色空间的位置和区域，是BCDS体系中重要的体系理论之一，是设计师设计色彩的应用指南。
The location and area for color psychology and color space is one of the important system theories in BCDS system and is application guidance for designer to design color.
