New look in the living room

I am doing some redecorating in my living room and am thinking of using these 3 colors. I will do pelmet boxes above my windows in a coral print fabric, royal blue print fabric as throw pillow covers, and brown throw pillows. What do you think? I am a little nervous but really want something new in this room! I want it to feel fun and light but still mature...does that make sense and do these colors lend to that sort of atmosphere? Let me know what you think of these colors and any suggestions you may have.
