Today me and my friend were talking about how Lucy's fairy tail mark was pink and of the ship NaLu but we were wondering what Natsu's color meant so we looked it up and everyone was saying it was for Erza.
My friend said "It's probably means that Natsu and Erza are meant to be together." And I got really mad because I love NaLu so I put some thought in it and came up with Natsu's Guild Mark is read to remind him of Igneel. Please tell me I wasn't the only one thinking about this.( Or the red is suppose to stand for flames)
