how do i get the current color of background()?

originalsurfmex

I would like to put a loop in my code that checks the background color so that it changes depending on what color it currently is.

How do I do that?

when you set background, save the value you set.

color bkColorGlobal; 

void setup() {
  setBkColor ( color(176, 222, 22) );
  println ("Color: "+colorAsString(bkColorGlobal)+".");
}

void draw () {
  //
}

void setBkColor (color bkColLocal) {
  bkColorGlobal = bkColLocal;
  background(bkColLocal);
}

String colorAsString (color bkColLocal) {
  return int(red(bkColLocal))+ ":" + 
    int(green(bkColLocal) )+ ":" + 
    int(blue(bkColLocal));
}
//
