wall sticker cherry

so my walls are like a medium shade of pink. we have carpet. i can;t repaint but i can change the carpet. i want to redesign my entire room to make it more like me. what color carpet should i get? my furniture is all like a cherry brown and i have a tan desk. i also want to rearrange my room around. any suggestions and/or ideas. it would really help me. thanks. and i already know about those sticker thingys you stick on the walls. btw my style is like fun, bright, neon colors. also i dont mind like the natural and boho theme either. i wanted to do brown carpet but i changed my mind after i thought it would clash with my furniture. what color goes with pink? and my favorite color is yellow. so maybe we can add a splash of yellow somewhere. =]
my mom would never let me get white carpet. and keep in ind... i'm a freshman and only 14. there's only so much i can do... so nothing drastic
and i have pink and lime curtains... =]
