Hello all, I am starting a processing project for school and I want the circle to randomly change color (either red, blue or green) everytime it is mousepressed.
```auto
def setup():
size(500, 500)
global x, y, speed, acceleration, bgImage
x, y = -50, -50
speed = 2
acceleration = 0.4
bgImage = loadImage("backgroundimage.jpeg")
def mouseReleased():
global x, y, speed
x = mouseX
y = mouseY
speed = 1
def draw():
noStroke()
global x, y, speed, bgImage
image(bgImage, 0, 0, width, height)
fill(random?) # here
ellipse(x, y, 40, 40)
y = y + speed
speed = speed + acceleration
fill(0, 255, 0)
rect(400,390,20,100)
fill(255, 0, 0)
rect(350,350,20,100)
fill(0, 0, 255)
rect(200,330,20,100)
```

You’ll want to combine the `random()` and `fill()` functions –

Also, if you want the color to be fixed if you have not pressed the mouse, you may want to have a global variable, something like `fill_color`, to keep the color, and the `color()` function will build a color for you to store that you can change when you press the mouse…
```python
fill_color = color(100, 100, 200) # blueish start
def draw():
noStroke()
global x, y, speed, bgImage
image(bgImage, 0, 0, width, height)
fill(fill_color)
...
def mousePressed():
global fill_color
fill_color = color( ... )
```

Thank you! I put this into my code using `fill_color = color(255, 0, 0)`, but say I don’t want it just to be red, I want it to be green sometimes and blue sometimes (randomly), how do I do that? I tried using the `random()` function but the color changes too quickly

I didn’t want to spoil your research, but see if this makes sense:
```python
def mousePressed(): # this will run once in the event of the mouse being pressed
global fill_color
fill_color = color(random(256), random(256), random(256))
```
