Yes, but in this case it makes the whole rectangle fill black, I want the rectangle colour to be different from text colour

I know

you have to say

```auto
fill ..... // set the color you want to have for the rect 
rect......
fill(0); // black 
text.......

```

for both situations, red light and green light…

You introduced another problem by removing the code from your post and changing topic title.

Please restore it.

Here is the last edit you removed:

## 

~~Very~~~~ basic ~~~~traffic~~~~ light~~

NAproblemsolved

boolean changeColour;

void setup() {  
changeColour = false;  
textSize (46);  
size (240, 300);  
}

void draw() {  
rect (40, 40, 160, 200);  
stroke (1);  
if (changeColour) {  
fill (0,200,0);  
text(“Walk”, 70, 150);  
}  
else

{ fill (200,0, 0);  
text(“Stop”, 70, 150);  
}  
}  
void mousePressed()  
{  
changeColour = !changeColour;  
}

**How do I make the text black so you can actually see it?**
