Hello CallahLily,
Well I can't speak for everyone, but I believe theres nothing wrong with that all. Everyone takes initiation differently. I know when I got initiated you couldn't find me in anything but my Harvard Red, and Old Gold colors. I even had pajammas...said to say. I love my fraternity, so I believe he's just the same way. I dont think you have to start worrying just yet....wait to see if he only drinks things that remind him of his colors..for me I stuck with Cherry Red koolaid

and Mango Lemonade

WOW talk about out of it. But it was a phase...well atleast that part

I still wear everything. Hope this helps!
Phi Kappa Tau fo life,
