RGB LED, guidence! (New arduino user)

I have been programming with Processing and for 3-4 weeks I bought my first Arduino...

I just bought RGB LEDs and I want to put in a value like i could do in Processing...

I found this: http://arduino.cc/en/Reference/EsploraWriteRGB

But i need the Esplora.h file, i was wondering if its possible to somehow write similar to the reference in the URL..? (without the Esplora.h file)

Like:

digitalWrite(ledPin, HIGH(255,255,0);

or something like that?

// Pick the three PWM output pins that the RGB LED is connected to.
const int redPin = 3;
const int greenPin = 5;
const int bluePin = 6;

void setup() {
    pinMode(redPin, OUTPUT);
    pinMode(greenPin, OUTPUT);
    pinMode(bluePin, OUTPUT);
} 

void loop()
{
 writeRGB(0, 128, 255);
 delay(1000);
 writeRGB(255, 0, 128);
 delay(1000);
 writeRGB(128, 255, 0);
}

void writeRGB( int red, int green, int blue) {
    analogWrite(redPin, red;
    analogWrite(greenPin, green);
    analogWrite(bluePin, blue);
}

// Pick the three PWM output pins that the RGB LED is connected to. const int redPin = 5; const int greenPin = 10; const int bluePin = 9;

void setup() { pinMode(redPin, OUTPUT); pinMode(greenPin, OUTPUT); pinMode(bluePin, OUTPUT); }

void loop() { writeRGB(255, 255, 255); //White

}

void writeRGB( int red, int green, int blue) { analogWrite(redPin, red); analogWrite(greenPin, green); analogWrite(bluePin, blue); }
