左颊肝之部也，右颊肺之部也，额上心之部也，颏下肾之部也，鼻者脾之部也。本部见五色，或浅淡不

黄、赤为阳色，主风主热。青、白、黑为阴色，主寒主痛。若黑甚在脉则麻痹，在筋则拘挛。微黑色，
主肾病水寒。若浅淡白色，主大吐衄下血脱血，若不吐衄下血，则为心不生血，血不荣于色也。痿黄色，主诸

肝化青色，其病善怒，脐左动气，转筋胁疼，诸风掉眩，疝气耳聋，此皆肝实之病也。若肝虚则目视KT

舌是心的外窍，舌色发红是心病的表现。舌色深红且焦枯卷缩的，属于邪气实证；舌色浅红且短小的，属于正气虚证。鼻是肺的外窍，鼻色发白是肺病的表现。鼻色深白且伴有气喘、胸部胀满的，属于邪气实证；鼻色浅白且仅有气喘而无胸部胀满的，属于正气虚证。眼睛是肝的外窍，目色发青是肝病的表现。目色深青的，属于邪气实证；目色浅青的，属于正气虚证。口唇是脾的外窍，唇色发黄是脾病的表现。唇色深黄的，属于邪气实证；唇色浅黄的，属于正气虚证。耳朵是肾的外窍，耳色发黑是肾病的表现。耳色深黑的，属于邪气实证；耳色浅黑的，属于正气虚证。
左脸颊是肝的对应部位，右脸颊是肺的对应部位，额头是心的对应部位，下巴是肾的对应部位，鼻子是脾的对应部位。在这些相应部位出现五色变化，无论是颜色浅淡不足，还是颜色深浓过度，都属于病色。例如，在属脾的鼻部见到黄色本色，这是本经自感邪气的病变；如果见到白色，这是子盗母气导致的虚邪病变；如果见到赤色，这是母助子气导致的实邪病变；如果见到青色，这是相克太过（贼邪）的病变；如果见到黑色，这是相克不及（微邪）的病变。其余情况可仿此类推。
黄色和赤色属于阳色，主风证和热证。青色、白色和黑色属于阴色，主寒证和痛证。如果黑色过重，出现在脉象上则表现为麻痹，出现在筋脉上则表现为拘挛。轻微的黑色，主肾病及水寒之邪。如果是浅淡的白色，主大吐、鼻衄或便血等失血导致的脱血证；如果不发生吐衄下血，则是由于心不生血，血液不能荣润面色所致。萎黄的颜色，主各种虚损性疾病。两颧呈现深红色，主阴火上乘，属于虚损劳疾。
肝化为青色，其病症表现为易怒，脐左侧有动气，筋脉抽搐胁肋疼痛，各种风证引起的震颤眩晕，疝气耳聋，这些都是肝实证的病变。如果肝虚，则视物模糊不清而看不见东西，胆小惊恐，好像有人要抓捕自己一样。心化为赤色，其病症表现为易喜，脐上有动气，心胸烦闷疼痛，舌红口干，健忘惊悸，怔忡不安。如果热邪乘于心导致心实，则会发狂昏冒。如果神气怯弱导致心虚，则会凄惨悲伤。脾化为黄色，其病症表现为易忧，当脐处有动气，思虑过多食欲减退，倦怠乏力，腹部胀满肠鸣，腹痛并伴有腹泻，这些都是脾虚证的病变。如果脾实，则身体沉重、腹部胀满、大便闭塞。肺化为白色，其病症表现为易悲，脐右侧有动气，恶寒发热，咳嗽吐痰喷嚏，气喘呼吸急促，皮肤疼痛胸痹。如果肺虚，则气喘咳嗽气短，气息不能接续。肾化为黑色，其病症表现为易恐，脐下有动气，腹部胀满水液停聚，浮肿胀满或气喘，小便不利，腰背骨骼疼痛，频繁打哈欠，心中空虚如饥饿感，足部寒冷厥逆。
The tongue is the external orifice of the Heart (Xin, 心). Red coloration of the tongue indicates a disease of the Heart. A deep red and dry, curled tongue signifies an Excess syndrome (Excess pathogenic factor); a pale red and short tongue signifies a Deficiency syndrome (Deficient healthy qi). The nose is the external orifice of the Lung (Fei, 肺). Whitening of the nose indicates a disease of the Lung. Deep white coloration with panting and chest fullness signifies an Excess syndrome; pale white coloration with panting but without chest fullness signifies a Deficiency syndrome. The eyes are the external orifice of the Liver (Gan, 肝). Greenish discoloration of the eyes indicates a disease of the Liver. Deep green signifies an Excess syndrome; pale green signifies a Deficiency syndrome. The lips are the external orifice of the Spleen (Pi, 脾). Yellowing of the lips indicates a disease of the Spleen. Deep yellow signifies an Excess syndrome; pale yellow signifies a Deficiency syndrome. The ears are the external orifice of the Kidney (Shen, 肾). Blackening of the ears indicates a disease of the Kidney. Deep black signifies an Excess syndrome; pale black signifies a Deficiency syndrome.
The left cheek corresponds to the region of the Liver; the right cheek corresponds to the region of the Lung; the forehead corresponds to the region of the Heart; the chin corresponds to the region of the Kidney; the nose corresponds to the region of the Spleen. If any of the five colors appear in these corresponding regions, whether too pale or too intense, they are all pathological colors. For example, if the nose (the region of the Spleen) shows its own yellow color, it indicates a self-disease of the channel due to pathogenic factors. If white is seen, it indicates a Deficiency evil caused by the "child stealing from the mother" (Lung metal draining Spleen earth). If red is seen, it indicates an Excess evil caused by the "mother assisting the child" (Heart fire generating Spleen earth). If green is seen, it indicates a "robber evil" (Wood overacting on Earth). If black is seen, it indicates a "minor evil" (Water controlling Wood, here implying weak control or reverse restriction depending on context, specifically Kidney water affecting Spleen earth indirectly or via Wood). The rest can be deduced by analogy.
Yellow and red are Yang colors, governing Wind and Heat syndromes. Green, white, and black are Yin colors, governing Cold and Pain syndromes. If black is excessive, manifested in the pulse, it leads to numbness and paralysis; manifested in the sinews, it leads to spasms and contracture. Mild blackness governs Kidney disease and cold-water pathogens. Pale white governs severe vomiting, epistaxis, or lower bleeding leading to blood loss syndrome; if there is no vomiting, epistaxis, or lower bleeding, it indicates that the Heart fails to generate blood, and blood fails to nourish the complexion. Withered yellow governs various deficiency diseases. Deep red on both cheeks governs flaming up of deficient fire, indicating consumptive labor diseases.
The Liver transforms into green. Its diseases include irritability, pulsation at the left side of the umbilicus, tendon cramps and hypochondriac pain, various wind syndromes causing tremors and vertigo, hernia, and deafness; these are all Liver Excess diseases. If the Liver is deficient, vision becomes blurred and unclear, fearfulness and timidity occur, resembling the sensation of being pursued. The Heart transforms into red. Its diseases include excessive joy, pulsation above the umbilicus, vexation and pain in the heart and chest, red tongue with dry mouth, forgetfulness, palpitations, and restlessness. If heat overwhelms the Heart causing Excess, madness and stupor may occur. If spirit is timid and the Heart is deficient, sorrow and weeping may prevail. The Spleen transforms into yellow. Its diseases include excessive worry, pulsation at the umbilicus, excessive thinking with poor appetite, fatigue and weakness, abdominal fullness and borborygmus, abdominal pain with diarrhea; these are all Spleen Deficiency diseases. If the Spleen is Excess, the body feels heavy, abdominal fullness occurs, and constipation results. The Lung transforms into white. Its diseases include excessive sadness, pulsation at the right side of the umbilicus, aversion to cold and fever, coughing and expectoration, sneezing, panting and rapid breathing, skin pain, and chest bi-syndrome. If the Lung is deficient, panting, coughing, and shortness of breath occur, with inability to sustain respiration. The Kidney transforms into black. Its diseases include excessive fear, pulsation below the umbilicus, abdominal fullness with fluid retention, edema and fullness or panting, difficulty in urination, pain in the lower back and bones, frequent yawning, a feeling of emptiness in the heart as if hungry, and cold feet with cold limbs.
