Which color of pen is recommended for filling out a job application?

Using black or blue ink is recommended for filling out a job application because these colors are professional and universally accepted in formal documents. Black ink provides a clear and bold appearance, making text easy to read, which is crucial for ensuring that potential employers can easily review the application. Blue ink also stands out well, but it is less formal than black. Both colors convey seriousness and professionalism, which are important qualities in a job application context.

In contrast, colors like red, green, or purple may not be taken seriously in professional settings. Red can be perceived as aggressive or overly critical, which is not suitable for job applications. Green and purple are often seen as informal or whimsical, which might distract from the content of the application. Therefore, sticking with black or blue is the best practice for such formal documents.
