Where is the fault?

Hallo111

Hello, the following Code should be a small paint programm. My Problem is that I can't change the color and I don't know where the fault is. It would be great if somebody can help me! Thankyou and sorry for my bad english! Hallo111

int r=0;
int g=0;
int b=0;

void setup(){
  size(760,300);
  background(255,255,255);
  smooth();
  noStroke();
  fill(#808080);
  rect(0,0,100,300);
  stroke(0,0,0);
  fill(255,255,255);
  ellipse(25,25,30,30);
  fill(0,0,0);
  ellipse(75,40,30,30);
  fill(227,32,32);
  ellipse(25,75,30,30);
  fill(218,222,36);
  ellipse(75,90,30,30);
  fill(36,139,222);
  ellipse(25,125,30,30);
}
void draw(){
  if (mousePressed==true && mouseX>10 && mouseX<40 && mouseY>10 && mouseY<40){
    int r=255; int g=255; int b=255;
    println("white");
  }
  if (mousePressed==true && mouseX>60 && mouseX<90 && mouseY>25 && mouseY<55){
    int r=0; int g=0; int b=0;
    println("black");
  }
  if (mousePressed==true && mouseX>10 && mouseX<40 && mouseY>60 && mouseY<90){
    int r=227; int g=32; int b=32;
    println("red");
  }
  if (mousePressed==true && mouseX>60 && mouseX<90 && mouseY>75 && mouseY<105){
    int r=218; int g=222; int b=36;
    println("yellow");
  }
  if (mousePressed==true && mouseX>10 && mouseX<40 && mouseY>110 && mouseY<140){
    int r=36; int g=139; int b=222;
    println("blue");
  }
  if (mousePressed==true && mouseX>100 && mouseX<760 && mouseY>0 && mouseY<300){
    fill(r,g,b);
    noStroke();
    ellipse(mouseX,mouseY,30,30);
  }
}

Inside all of those mousePressed conditionals you are doing:

int r=255… etc.

This makes a temporary integer r and does not overwrite the r that you want. Instead do:

r=255… etc.

Yes, that's the solution! Thankyou
