The sign is a solid matte black color and has words written on it. The words are written in yellow capital letters slightly above the center of the screen and ask, "Under 17, what are the criteria for viewing with caution?". Further below, in bold white letters, it says, ``↓ Is the cat surfing more dangerous than the image below? www.'' The signboard is a simple one-color black, and the contrast of each letter stands out clearly.
