How to make sure 3D light does not affect UI text?

Hi everyone,
I am new to Processing and I was playing with 3D rendering in processing. I have a ball move around following the mouse. The scene is lit by a point light. I have some text on the screen that shows the position of the ball in the space. But the texts are affected by the point light as well. I was wondering is there a way to exclude the texts from the lighting?
Below is my code.
Thank you for your help in advance.
3d_ball.pde
------------------------------------------
Walk w1 = new Walk();
float mouseZ = 0.0;
PFont font;
void setup() {
size(800, 320, OPENGL);
smooth();
noStroke();
fill(255);
font = createFont("SegoeWP", 14);
textFont(font);
textAlign(LEFT);
//pointLight(255, 244, 178, width/2, height/2, 10);
}
void draw() {
background(50);
pointLight(255, 244, 178, width/2, height/2, 100);
if(mousePressed) {
mouseZ -= 1;
} else {
mouseZ = 0;
}
text("x: " + mouseX, 10, 20);
text("y: " + mouseY, 10, 40);
text("z: " + mouseZ, 10, 60);
w1.update(mouseZ);
}

Walk.pde
---------------------------------------------------
class Walk {
float x, y, z;
float speedX, speedY, speedZ;
Walk() {
x = width/2;
y = height/2;
z = 0.0;
speedX = 0.0;
speedY = 0.0;
speedZ = 0.0;
}
Walk(float x, float y) {
x = width/2;
y = height/2;
z = 0.0;
speedX = 0.0;
speedY = 0.0;
speedZ = 0.0;
}
void step(float mz) {
float distanceX = mouseX - x;
float distanceY = mouseY - y;
float distanceZ = mz - z;
speedX = distanceX/10;
speedY = distanceY/10;
speedZ = distanceZ/10;
x += speedX;
y += speedY;
z += speedZ;
}
void update(float mz) {
step(mz);
pushMatrix();
translate(x, y, z);
sphere(20);
popMatrix();
}
}
