Changes in nail colour can sometimes indicate underlying health issues. For example, pale or white nails can indicate anaemia or liver disease, while yellow nails may be a sign of a fungal infection or psoriasis. Bluish nails can indicate poor circulation or respiratory issues, and a greenish-black discolouration could be a sign of a bacterial infection. Healthy nails are typically pink with a white half-moon shape at the base, known as the lunula.

Yellow nails
Changes in nail colour can sometimes indicate underlying health issues. Yellow nails, for instance, may be a sign of a fungal infection or psoriasis. They can also be caused by chronic lung disease or cancer. In adults, yellow nails are thickened and yellowish-green, with the lunula no longer visible and the cuticle lost. In children, yellow nails occasionally occur but are not usually a cause for concern. However, if you are worried about any sudden changes in your nail colour, it is important to seek medical attention as soon as possible.
In addition to indicating underlying health issues, changes in nail colour can also be a result of external factors such as smoking or exposure to certain chemicals. For example, people who smoke cigarettes may notice that their nails become stained a yellowish colour over time. This discolouration is caused by the tar and nicotine in cigarette smoke, which can build up on the nails and skin. Similarly, exposure to certain chemicals in cleaning products, nail polish, or other cosmetics can also cause nail discolouration.
While yellow nails can sometimes be a cause for concern, it is important to remember that they do not always indicate a serious health issue. In some cases, yellow nails may be a result of harmless factors such as frequent nail polish use or exposure to certain dyes or pigments. Additionally, yellow nails can sometimes be a normal variation in nail colour, especially in people with darker skin tones. However, if you are concerned about any changes in your nail colour, it is always best to consult a doctor or dermatologist for a proper diagnosis.

Greenish-black nails
Changes in nail colour can sometimes indicate underlying health issues. Greenish-black nails, for example, can be a sign of a bacterial infection. Nails that are completely black can be caused by injury, or, in some cases, indicate damage to the nail matrix, the area where the nail first begins to form.
If you notice any changes in your nail colour, it is important to consult a doctor as soon as possible to get a diagnosis. While some nail colours indicate a simple deficiency, others can be more serious. For instance, red nails could mean possible heart disease or kidney issues, while blue nails are a sign of poor oxygen circulation, heart or lung issues. A vertical black stripe from the cuticle to the tip can be the most serious of all, as it may indicate subungal melanoma, a dangerous form of skin cancer.
