What color ink is typically used for entries in the logbook?

The standard practice for entries in a logbook typically requires the use of blue or black ink. This convention is rooted in the desire for clarity and permanence. Blue and black inks are more legible and provide a clear contrast against the white pages of the logbook, ensuring that the entries can be read easily and accurately. Additionally, these colors are generally accepted as professional standards across various formal documentation practices.

Using blue or black ink also helps to maintain consistency in the documentation process, which is crucial for maintaining accurate records. In contrast, colors like red, green, or purple could be interpreted as being used for specific purposes, such as highlighting or marking errors, rather than for formal entries. Thus, blue or black remains the preferred choice for official logbook documentation.
