A lot of people are asking about the meaning of the letters, here it is:
Red is the color of love, and so the heart carries it. It is a singular thing, meant to stand out. The words for the two people (me, I, you) are colored ocean blue, as that is my favorite color, and a color that has always connected me to the world.
It also stands for chatting, because in some chats such as Trillian, one name is red and one is blue. So it aims at relationships that begin or exist online, which is a tough thing.
This is not meant as a personal deviation, this is general
