Blue is the online alias of Simon Spier's secret pen-pal, and later, boyfriend. The name "Blue" was taken from his email address, email@example.com.
Blue comes out as gay on his high school's Tumblr page. Soon, Simon emails him under the alias of "Jacques", telling him that he is also gay. The boys begin an email-only relationship, that eventually turns into mutual attraction.
There are a few guys throughout the book and movie that Simon suspects are possibly Blue.
Bram is a classmate and friend of Simon. He sits at Simon's lunch table. At the carnival, Bram reveals himself to be Blue, saying that he gave it away all along, as his email address consisted of bits of his full name, and his birthday (Abraham Louis Greenfeld, January 18th = blugreen118)

Martin is the student who blackmails Simon once he discovers his secret. At the carnival, Martin tells Simon that he is Blue, but then admits he is lying and only told him because he felt bad that the real Blue hadn't shown up.
