I recently created this room lighting project to make my paintings with ghost paint look better at night. I converted the painting into a remote using the color sensor.

Arduino uno R3

Jumper wires

TCS3200 color sensor

5V RGB Led strip

5V 2A Adapter

12V 1A Adapter

1k resistance x3

TIP31 Transistor x3

Insulating tape

Nano tape

Wooden frame

#define s1 9
#define s2 10

#define LED_G 5
#define LED_B 6

                                               //e.g: if the "Red" value given by the sensor is 15 -> it will generate a pwm signal with 255 value on the LED_R pin same for 60->0, because the lower the value given by the sensor the higher is that color
