A beta's eyes will turn blue if they take the life of an innocent person, in Derek's case, it happened the night that Paige rejected the bite and so Derek killed her to relieve her of the pain she was enduring because of the rejection.

This is not against you, since you gave the correct answer. Blue eyes when you kill an innocent? And what about Allison's mother. She is a hunter and has killed innocents. Being a werewolf doesn't change the fact that those she killed she killed because of something they could not influence. Those hunters are the worst racists/speciesists ever. This means that all werewolfs with yellow eyes are inherently innocent and even those with blue eyes are not necessarily evil. Also taking Paiges live-an innocent life-was a mercy killing and can't be taken as murder. Also what do they mean with innocent? Who specifies what innocent means? What if its self-defense or an accident? I think the whole idea is ludricous.
His eyes are blue because Derek took an innocent life (Paige). His eyes used to be red when he was an alpha, but he went back to being a beta to save Cora.
Derek's eyes turned Blue because he had taken the life of his childhood crush Paige to end her suffering after she was bitten Ennis and was rejecting the bite.
