tried uploading code but continues to give me this error message 'LEDred' was not declared in this scope

here is my code:

void setup()
// put your setup code here, to run once:
{

pinMode(LEDred, OUTPUT);
pinMode(LEDgreen, OUTPUT);
pinMode(LEDblue, OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:

}
analogWrite(LEDgreen, brightnessgreen); //Green and red on = yellow
analogWrite(LEDred, brightnessred);
delay(b);
analogWrite(LEDgreen, dark); //Green and red off = yellow off
analogWrite(LEDred, dark);
analogWrite(LEDgreen, brightnessgreen); //Green and blue on = turquoise
analogWrite(LEDblue, brightnessblue);
delay(b);
analogWrite(LEDgreen, dark); //Green and blue off = turqouise off
analogWrite(LEDblue, dark);
analogWrite(LEDred, brightnessred); //Red an blue on = purple
analogWrite(LEDblue, brightnessblue);
delay(b);
analogWrite(LEDred, dark); //Red and blue off = purple off
analogWrite(LEDblue, dark);

This is not a bootloader issue.

I can't see where any of your LED pin numbers are defined.

And when you've fixed that, the compiler will have all sorts of messages about the fact that you don't have code in loop()
