RGB Accent Lighting with Crown Molding for Office Lighting

I'm looking to add RGB accent LED strip lighting to about 54 ft around three walls for my office room that is 22x10. I have purchased some crown molding (Orac Decor CX190). What would you recommend? I would think I can do two separate runs from the unlit 10ft wall to help cover the existing 54 feet. But I see most strands come in 16ft lengths. 

Unfortunately, we do not offer full RGB product solutions at this time. As such, you will likely need to work with third-party suppliers to purchase a dimmer, controller and power systems.

We do offer full solutions for white LED strip lights (static color). If there is any interest here, we would be more than happy to provide product and solution recommendations.
