Repainting my room?

My walls are pink! Yes, so girly right? I've been wanting to paint my walls another color for a while but since I share a room with my sister it's kind of hard to paint it another color that she'll like too. But I don't care, I'm just going to paint it whatever color I want. I want something more mature, more my age you know? lol.. Pink is more for girls 13 and younger, ha ha. So I was thinking about this color? Let me know what you all think!!!! Your feedbacks can help!

This is like a light teal color. It's so pretty! And I'm trying to find these bedding spread! TARGET?!?!?
