CW for spoilers for books 4-5 and 10-13 of the manga series Witch Hat Atelier, if you have not read these books, you have been warned for spoilers and cannot yell at me if you didn't want spoilers if you continue to read.
what if- and hear us out on this one- what if Qifrey's hair is white bcz of the forbidden magic that was used on him? just like- what if is hair used to be a different color but rapidly turned white cuz of what was done to him? we know it doesn't make much sense but Custas' eyes are lighter than they originally were when we were first introduced to him but his eyes only started to get light AFTER Ininia used forbidden magic him that physically altered his body?
"but Qifrey's hair is white and his eyes surely didn't change color too" I hear you in the back saying, but what if Custas' hair gets lighter? hm? that proves my theory and also- we see Qifrey mention that his left eye is getting increasingly worse and becoming more sensitive to light, so that proves that there's a chance his eye also changed color the same way Custas' are!!
either that or I'm completely wrong idk but we don't see any other way this would happen or make sense so
