Avoiding Color Gradients in Passport Photos

A color gradient or color transition is a series of colors that depend on their position.

There are two types of color gradients. A linear color gradient is characterized by two points, each with a different color. A circular color gradient is a circle with a certain color, and another color in the focus.

Color gradient is the opposite of a solid color.

Rules for Color Gradients in the Background of a Passport Photo

The government has established rules for the background of passport photos. These rules state that the photo must have a solid background, and the lighting also plays an important role.

The requirements for the background are:

• The background must be solid.
• The background must be bg_color.
• The background must be uniform.
• There should be no color gradient visible in the background.
• There must be sufficient contrast between the subject's head and the background.
