Green ink?

Question

I know blue and black ink are used for pretty much everything, and red ink is used to correct papers, but what is green ink used for?

Answer 1

Drawing? *shrug* It can be used for pretty much anything, I guess, just like any other writing utensil.

Answer 2

Different people have different preferences. For those who likes the colour green, they can use it to underline words of sentences. They can use it for drawing too. And maybe can use it to write the correct words.

Eg. You use black and blue to write, red to mark in terms of ticks and crosses and green to put in the correct word.

Its all up to individuals.
