我认为五色交错出现，有分别显现的情况，也有间隔显现的情况。通过五行的生克关系进行推导，从而判断病情的吉凶。所谓“分见”，是指面部六部（左颊、右颊、额、颏、鼻）的颜色彼此不同。例如青色与赤色分别显现，赤色与黄色分别显现，黄色与白色分别显现，白色与黑色分别显现，黑色与青色分别显现，这属于五行相生的颜色表现。青色与黄色分别显现，黄色与黑色分别显现，黑色与赤色分别显现，赤色与白色分别显现，白色与青色分别显现，这属于五行相克的颜色表现。
所谓“间见”，是指五种颜色的色泽相互叠加、混杂。例如青色与赤色相间显现，赤色与黄色相间显现，黄色与白色相间显现，白色与黑色相间显现，黑色与青色相间显现，这属于五行相生的颜色表现。青色与黄色相间显现，黄色与黑色相间显现，黑色与赤色相间显现，赤色与白色相间显现，白色与青色相间显现，这属于五行相克的颜色表现。凡是相生者，病情为顺；凡是相克者，病情为逆。然而，这些情况都有深浅之分，因此也各有虚证和实证的区别。必须观察面色是润泽还是枯槁，然后才能决定预后的成败。如果面色枯槁而无光泽，即使是相生之象也难以调治；如果面色润泽而不枯槁，即使是相克之象也可以救疗。关键在于要符合四时季节的变化，并结合“十法”进行明辨，不要机械地按图索骥。
望诊的方法中，五色交错的原理已在前面论述过，“十法”合参的内容将在后面讲解。考察气色，区分生克，固然可以知道病情的顺逆和症状的从违。进而结合“浮沉”之法，就能知道病位在表还是在里；结合“清浊”之法，就能知道病性属阴还是属阳；结合“微甚”之法，就能知道病势属虚还是属实；结合“散抟”之法，就能知道病程的久暂（远近）；结合“泽夭”之法，就能知道预后的好坏（成败）。再结合气色来具体分析：例如面色红赤，主热证；红赤而浅淡的，是虚热证；红赤而深重的，是实热证。浅淡的红赤且脉色浮显的，是虚热在表；浅淡的红赤且脉色深沉的，是虚热在里；深重的红赤且脉色浮显的，是实热在表；深重的红赤且脉色深沉的，是实热在里。如果再结合“清浊”来分析，就能知道病变所在的脏腑；结合“散抟”来分析，就能知道病情的轻重；结合“泽夭”来分析，就能知道病情的吉凶。这样，五官六部以及四时五色，都可以错综综合地参考观察。像这样，疾病的传变规律，不也就清楚明白了吗？虽然如此，病情深奥，望诊方法精微，有时病症隐藏在此处却显露在彼处，疾病往往还有隐蔽的情状。因此，必须将脉象与症状互相参照，在声音方面进行错综分析，观察达到极其精细，询问达到极其确切，然后才能确诊疾病。
I hold that the intermingling of the five colors presents two modes: distinct manifestation and intermittent manifestation. Through these, the mutual generation (Sheng) and mutual restriction (Ke) of the Five Elements are deduced, and thus the auspiciousness or inauspiciousness is determined. By "distinct manifestation," it is meant that the colors of the six facial regions differ from one another. For instance, when blue-green (Qing) and red (Chi) appear distinctly, or red and yellow (Huang), yellow and white (Bai), white and black (Hei), or black and blue-green, these represent the color manifestations of mutual generation. Conversely, when blue-green and yellow, yellow and black, black and red, red and white, or white and blue-green appear distinctly, these represent the color manifestations of mutual restriction.
By "intermittent manifestation," it refers to the overlapping and mixing of the five colors. For example, when blue-green and red, red and yellow, yellow and white, white and black, or black and blue-green appear intermixed, these correspond to the mutual generation of colors. When blue-green and yellow, yellow and black, black and red, red and white, or white and blue-green appear intermixed, these correspond to the mutual restriction of colors. Generally, mutual generation indicates a favorable course (Shun), while mutual restriction indicates an unfavorable course (Ni). However, each case has its depth and superficiality, corresponding to deficiency (Xu) and excess (Shi) patterns respectively. One must observe whether the complexion is lustrous (Ze) or withered (Yao) to determine the outcome. If the color is withered and lacks luster, even if it follows the pattern of mutual generation, it will be difficult to treat. If the color is lustrous and not withered, even if it follows the pattern of mutual restriction, it may still be curable. The key lies in aligning with the four seasons and analyzing thoroughly using the Ten Methods, avoiding mechanical application without critical judgment.
The method of inspection (Wang Zhen) regarding the intermingling of the five colors has been discussed previously; the integration of the Ten Methods will be explained subsequently. Examining the Qi and color, and distinguishing between generation and restriction, allows one to ascertain the favorability or unfavorability of the disease and the compliance or deviation of symptoms. Furthermore, by applying the Method of Floating and Sinking (Fu Chen), one can determine whether the pathogen is in the Exterior (Biao) or Interior (Li); by applying the Method of Clear and Turbid (Qing Zhuo), one can identify Yin (Yin) or Yang (Yang) nature; by applying the Method of Subtle and Severe (Wei Shen), one can assess Deficiency (Xu) or Excess (Shi); by applying the Method of Scattered and Congested (San Tuan), one can estimate the duration (proximity or remoteness) of the disease; and by applying the Method of Lustrous and Withered (Ze Yao), one can predict the prognosis (success or failure).
Integrating this with specific color analysis: Red color indicates Heat (Re). A faint red indicates Deficient Heat (Xu Re); a deep red indicates Excess Heat (Shi Re). A faint red with floating characteristics indicates Deficient Heat in the Exterior; a faint red with sinking characteristics indicates Deficient Heat in the Interior. A deep red with floating characteristics indicates Excess Heat in the Exterior; a deep red with sinking characteristics indicates Excess Heat in the Interior. Combining this with Clear/Turbid analysis reveals the affected Zang-Fu organs (Zang Fu). Combining it with Scattered/Congested analysis reveals the severity of the condition. Combining it with Lustrous/Withered analysis reveals the auspiciousness or inauspiciousness of the disease. Thus, the five facial areas, six regions, and the five colors corresponding to the four seasons can all be comprehensively cross-referenced. In this manner, the transmission and transformation of the disease become clear.
Nevertheless, pathological conditions are profound, and inspection methods are subtle. Sometimes, signs hidden in one area manifest in another, meaning diseases often have concealed aspects. Therefore, one must cross-reference pulse diagnosis (Mai Zhen) and symptomatology, analyze voice and sound comprehensively, observe with extreme precision, and inquire with utmost accuracy before making a definitive diagnosis.
