Four rectangle buttons

Hello
I wanted to make 4buttons that show individual color. however, when I click on each of them all buttons are turned on together. I know my problem is with the draw event but I don’t know what should I do.
may I kindly ask you to help me?

color colA = color(125);
color colB = color(0,255,0);
color colC = color(0,0,255);
color colD = color(255,0,0);
color colE = color(120,0,200);
float colSwitch = 0;
float X = 740;
float Y = 740;
float x;
float y;

void setup()
{
size(740,740);
background(0);
}
void draw()
{

rect(0,0,X/2,Y/2);

rect(width/2,0,X/2,Y/2);

rect(0,height/2,X/2,Y/2);

rect(width/2,height/2,X/2,Y/2);

//line(width/2,0,width/2,Y);
//line(0,height/2,X,height/2);

}
void mousePressed()
{

if(mouseX > width/4-X/4 && mouseX < width/4+X/4 && mouseY > height/4-Y/4 && mouseY< height/4+Y/4 )
{
fill(colB);

}else if(mouseX > width/2 && mouseX<width/2+X/2 && mouseY > height/2-Y/2 && mouseY< Y/2)
{
fill(colC);
}else if(mouseX > width/4-X/4 && mouseX < width/4+X/4 && mouseY >height/2 && mouseY< Y)
{
fill(colD);
}else if(mouseX > width/2 && mouseX < width/2+X/2 && mouseY > height/2 && mouseY< Y)
{
fill(colE);
}

}

Why have you posted the same question twice. Once is plenty. Also please format your code, to improve readability. CTRL + E

PLEASE DELETE THIS DUPLICATE POST:

Im sorry its because of lack of the internet in my country

Because each button has a different color you have to set each color before drawing each rectangle

before each of the rect() commands say fill(…color ) ;

void draw()
{
   fill(colB);
   rect(0,0,X/2,Y/2);

   fill(colC);
   rect(width/2,0,X/2,Y/2);

   fill(colD);
   rect(0,height/2,X/2,Y/2);

   fill(colE);
   rect(width/2,height/2,X/2,Y/2);

Then in mousePressed()

say

colE=color(random(255),random(255),random(255));

or

colB=color(random(255),random(255),random(255));

etc.

Don’t use fill() in mousePressed() since you say that in draw().

@PARINAZ129,

I have shared these two with you in other posts:

Assuming you are working on a PC:

The references are available locally on your PC as well:

As a beginner you should be going through the tutorials and read all the references + related references for each function along with related examples:

You can also explore the examples (available locally on PC) to get some insight:

There is a learning curve to all of this and you have to invest some time in yourself.
