You remember that you’ve seen some girls with blue hair. You wonder if it will look nice on your roommate. You try something different as well. You say that your roommates hair is blue but starts of as a darker blue and gradually starts to get lighter and stops at a light blue. Your roommates hair starts to become dark blue. Her entire hair is dark blue though. This isn’t what you said which confuses you it should have worked. As you say this your roommates hair starts to get lighter at the tips similar to being dip dyed. It smooths out perfectly. It actually looks quite nice on your roommate, she seems to think so too. Maybe another colour you say to your roommate.
