This is really a fun project instead of controlling the RGB led from the potentiometer you can control it from android app, android app for this project was created using MIT app inventor, where you can move each slider that has assigned to the RGB values.
Mixed color can be viewed in the android app, the same color can be displayed in the RGB LED too.
Step 1: Components Need for This Project
1) Arduino uno
2) RGB LED
3) Bluetooth Module
4) connecting Wires
Step 2: Circuit Diagram
Make sure which RGB LED you are going to use for this project.
If the RGB led is a common cathode type then you have to connect the cathode pin to grond
if the RGB led is a common anode type then you have to connect the anode pin to power supply
Note: Refer to the circuit connection, Make sure you add 1k ohm resistor between your arduino to RGB LED
