Which ink color is appropriate for formal applications?

• A. Blue or Black ink
• B. Red ink
• C. Pencil
• D. Green ink

Answer: (A)

In formal documents, blue or black ink is the best choice because it presents a clean, professional look and remains easy to read and reproduce. Black ink offers the strongest contrast on white paper, which helps with readability, archiving, and official printing or scanning. Blue ink is also acceptable in many settings because it can help distinguish handwritten signatures from printed text while still looking formal.

Other colors aren’t ideal for formal applications. Red ink is typically used for corrections or markings, which signals edits rather than formality. Pencil isn’t permanent and can smear or fade, undermining the document’s legitimacy. Green ink is unconventional and not widely accepted for official forms, which can come across as unprofessional.
