What color ink should you use to fill out an application?

Using black ink to fill out an application is essential for several reasons. Black ink is universally accepted as a standard for filling out official documents due to its clarity and professionalism. It provides the best contrast on paper, ensuring that the text is easily readable and looks clean.

In many instances, applications are scanned or copied, and black ink maintains its legibility better than other colors, which can sometimes become difficult to read or might not photocopy well. Additionally, using black ink aligns with best practices and common requirements found in various application processes, highlighting each detail without ambiguity.

While blue ink is also acceptable in some cases, it is less common for formal documents. Red and green inks, on the other hand, may be seen as informal and are typically discouraged because they can be harder to read and may not convey the same seriousness as black ink does.
