Final answer:
Cyanotic skin appears bluish due to deoxygenation, pink skin can result from increased blood flow, and yellow skin indicates possible liver problems or pigmentation issues.
Explanation:
Cyanotic refers to an abnormal bluish color of the skin due to deoxygenation, which leads to blue skin, especially seen in cases of restricted oxygen supply like during breathing difficulties or heart issues. Skin can also turn as pink due to increased blood flow near the surface when capillaries dilate, allowing a pinkish tint from visible hemoglobin. On the other hand, yellow skin can be indicative of liver issues or certain diseases affecting skin pigment.
