I think techeilis on tzit tzis look beautiful. I dont wear them, but I equally dont understand the machlokes about them, especially since we daven about them each and every day.
If a chassidish rebbe poskins they know the creature that gives them the valid blue dye to make techeiles, then who is anyone else to disagree? Litvish certainly have numerous rulings on the same question.
Long story short, to all who wear techeilis, thank you. It is always a nice thing to see them.
