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.
• Document-Specific Requirements: Exact dimensions, head proportions, background colour, and measurement units depend on the selected country and document.
• 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.
