A healthy nail is __________.

A healthy nail typically appears slightly pink, which is a sign of good circulation and healthy tissue beneath the nail. This color comes from the nail bed's blood vessels and indicates that the nail is nourished and properly functioning. The slight pink hue is a natural characteristic of normal, healthy nails, reflecting their vitality and the overall health of the person.

While nails may vary slightly in color and texture among individuals, a healthy nail should not be described as deep red, which could suggest inflammation or other issues, nor should it be transparent, as transparency can imply a lack of pigment and possibly indicate underlying health conditions. Similarly, slightly rough surfaces are not indicative of health but rather may be associated with damage or conditions affecting the nails.
