Which of the following elements is NOT typically found in a form header?

A form header usually includes elements that help provide context about the form itself and aid the user in understanding its purpose. The typical elements found in a form header include a title, which clearly indicates what the form is about; form instructions, which guide the user on how to fill it out properly; and a logo image, which can signify the brand or organization associated with the form.

While background color can indeed play a role in the overall design aesthetic of the form, it is not a standard or essential element of the form header. The header is primarily concerned with providing important information and context—such as identifying the form and giving instructions—rather than focusing primarily on design attributes like color. Therefore, background color is not a typical component of a form header, making it the correct choice in this context.
