What does it mean if a wart is white?

A white wart typically indicates that it is a common wart caused by the human papillomavirus (HPV). The white color can result from the accumulation of keratin, a protein in the skin, or from the wart being dry and lacking moisture. While most warts are harmless, a change in color or appearance should be monitored, as it could signify an infection or other skin condition. If there's concern, consulting a healthcare provider is advisable.
