like this?:
Code:

int h=0, s=255,v=255;

void setup() {
  size(350,256);
  colorMode(HSB);
  for(int y=0; y < 256; y++)
    for(int x=0; x < 256; x++)
    {
      stroke(x,y,127);
      point(x,y);
    } 
  fill(h,s,v);
  noStroke();
  rect(310,0,40,height);
}




void draw() {
  for(int y=0; y < 256; y++) {
    stroke(h,s,y);
    line(270,y,300,y);
  }
  if(mousePressed){
    if(mouseX<256 && mouseY<256) {
      h = mouseX;
      s = mouseY;
    }
    else if(mouseX > 270 && mouseX < 300)
      v = mouseY;
    println("h: "+h+", s: "+s+" v: "+v);
    fill(h,s,v);
    noStroke();
    rect(310,0,40,height);
