Nothing gets sent to Arduino from Processing

I have a problem where I kwow that my bluetooth module (HC-05) is connected to a processing sketch, but nothing ever gets sent from the processing sketch,why?

No error messages but the info never gets sent over because I never see it in Arduino, where it would be printed to the Serial Monitor.

Full Processing Code:

import processing.serial.*;
import controlP5.*;

Serial myPort;
ControlP5 cp5;

int slider1 = 0;
int slider2 = 0;
int slider3 = 0;

void setup() {

size(800, 800);
cp5 = new ControlP5(this);
PFont roboto = createFont("Roboto-Bold.ttf", 1, true);
ControlFont font = new ControlFont(roboto, 28);
Controller Aslider1 = cp5.addSlider("slider1")
.setPosition(85, 100)
.setCaptionLabel("Red")
.setRange(0, 255)
.setWidth(191)
.setHeight(50);
cp5.getController("slider1").getValueLabel().setFont(font).align(ControlP5.LEFT, ControlP5.BOTTOM_OUTSIDE).setPaddingX(0);
cp5.getController("slider1").getCaptionLabel().setFont(font).align(ControlP5.RIGHT, ControlP5.BOTTOM_OUTSIDE).setPaddingX(0);

Controller Aslider2 = cp5.addSlider("slider2")
.setPosition(301, 100)
.setCaptionLabel("Green")
.setRange(0, 255)
.setWidth(191)
.setHeight(50);

cp5.getController("slider2").getCaptionLabel().setFont(font).align(ControlP5.RIGHT, ControlP5.BOTTOM_OUTSIDE).setPaddingX(0);

Controller Aslider3 = cp5.addSlider("slider3")
.setPosition(517, 100)
.setCaptionLabel("Blue")
.setRange(0, 255)
.setWidth(191)

println(hex(color(int(slider1), int(slider2), int(slider3))).toString().substring(2));
myPort.write(hex(color(int(slider1), int(slider2), int(slider3))).toString().substring(2));
myPort.clear();
}
}

pixels.show();

setColor(redBrightness, greenBrightness, blueBrightness);

}

void setColor(int red, int green, int blue) {
for (int i = 0; i < NUMPIXELS; i++) {
pixels.setPixelColor(i, red, green, blue);
}
}

Thanks for the help, cheers!
