Warts are usually visible to a naked eye examination. They protrude from the skin and are palpable. They are most commonly felt as raised bumps, but they may be so small that they often go unnoticed. Most of them are small in size (less than one centimeter). In some cases, however, they are larger than one centimeter.
Warts have many different shapes. Their color varies. They may be skin-colored or lighter (nearly white). Some warts are darker than the skin (more brown or gray). Genital warts on the mucosa (inside the labia, the vagina, cervix, and inside the anal canal) are pink or whitish.
