Katy is no stranger from dying her hair many colors, and I am all for that having pinkish hair myself. But this slime green reminds me of a time in my much younger days when I tried from something blue, that was definitely not supposed to be green, and it turned out a lot like this. I pretended I loved it for about a day…and then my mom helped me fix it. That said, to each her own. If she wants slime green, go for slime green Katy Perry. You do you.
