hi interesting project I offer you a solution based on esp8266 IoT module to control RGB led light stripes. the module can host a tiny webserver which I can use for serving web based user interface using web browser from any device. the web page will be based on bootstrap framework which allows the page to be scalable to fit any screen correctly. so you can control your LEDs from PC ,tablet, phone. I will be happy if we collaborate to build your solution.
