Painting Ideas for a teen bedroom?!?!?

Okay guys, I'm 14 now and my room has been the same since I was 8. So, I want a change. My room has 6 walls( I know weird). Anyway, the colors I want to use are lime green, light blue, and a purple that pops haha. So I want to know how I should paint my room with those colors. I kinda want the purple to be like my accent wall. Here's what I don't want: To live in a box. I hate when you walk into a room and you feel like it's closing in on you. So do you guys have any creative ideas or ways for me to paint my room? Any ideas are greatly appreciated. Thanks in advance :) ~ Elizabeth <3
