how to use rgb led on arduino code example

Example: arduino code to rgb led

int red_light_pin= 11;int green_light_pin = 10;int blue_light_pin = 9;void setup() {  pinMode(red_light_pin, OUTPUT);  pinMode(green_light_pin, OUTPUT);  pinMode(blue_light_pin, OUTPUT);}void loop() {  RGB_color(255, 0, 0); // Red  delay(1000);  RGB_color(0, 255, 0); // Green  delay(1000);  RGB_color(0, 0, 255); // Blue  delay(1000);  RGB_color(255, 255, 125); // Raspberry  delay(1000);  RGB_color(0, 255, 255); // Cyan  delay(1000);  RGB_color(255, 0, 255); // Magenta  delay(1000);  RGB_color(255, 255, 0); // Yellow  delay(1000);  RGB_color(255, 255, 255); // White  delay(1000);}void RGB_color(int red_light_value, int green_light_value, int blue_light_value) {  analogWrite(red_light_pin, red_light_value);  analogWrite(green_light_pin, green_light_value);  analogWrite(blue_light_pin, blue_light_value);}
