RGB LED and servo trouble

Projects Programming
1

I have a simple setup with a problem. I have a single RGB LED, common ground, connected and working properly. When I add a servo, the LED stops illuminating. The program is running correctly, because I am getting debug information and the servo works. It's just that the LED stop illuminating.

I have tried two different Arduino boards, and two different servos, with the same results. The LED stops working when I try to attach the servo to a pin. Regardless of the pin. Comment out "servoWings.attach(6)" and the LED works properly. Understandably, though, the servo won't work without that. Any ideas?

Here is my code:

#include <Servo.h>

// pins for RGB LED
const int RED = 9;
const int GREEN = 10;
const int BLUE = 11;

// declare on object for the servo
Servo servoWings; 

int initFlag = 0;
void setup() {
  // put your setup code here, to run once:
  servoWings.attach(6);

  pinMode(RED, OUTPUT);
  pinMode(GREEN, OUTPUT);
  pinMode(BLUE, OUTPUT);

  Serial.begin(9600);

}

void loop() {
  // put your main code here, to run repeatedly:
  setLevel(0);
  Serial.println("Off");
  servoWings.write(100);
  delay(1000);
  servoWings.write(0);
  delay(1000);

  setLevel(1);
  Serial.println("Yellow");
}

void setLevel(int level) {
  if (level == 0) {
    analogWrite(RED, 0);
    analogWrite(GREEN, 0);
    analogWrite(BLUE, 0);
  } else if (level == 1) {
    analogWrite(RED, 500);
    analogWrite(GREEN, 125);
    analogWrite(BLUE, 0);
  }
}

const int RED = 9;
const int GREEN = 10;

The Servo library disables PWM (analogWrite) on pins 9 and 10. See the Servo library reference. Move your LED to other PWM pins.

Thank you! RTFM. After coding for 32 years, I should know that one.
