Hi!  
Sorry for another post on changing stimulus color. I read this very helpful post: [How to make polygons change color when pressed](https://discourse.psychopy.org/t/how-to-make-polygons-change-color-when-pressed/19282) on the change of a polygons’ color when the mouse is clicked on that polygon.  
I created a simple white rectangle. When I click on the rectangle it changes its color to red. This works fine with the following code:

```auto
if mouse.isPressedIn(rectangle):
    rectangle.fillColor = 'red'

```

However, when I try to implement the possibility that the red rectangle becomes white again when I press it another time the following code does not work. The red rectangle stays red (without flickering). I know that a flickering stimulus is another problem but I want to basically understand what is wrong with my code (I also tried the code of Becca in the post above but this one also does not work)

```auto
if mouse.isPressedIn(rectangle):
        if rectangle.fillColor =='red':
            rectangle.fillColor = 'white'
        else:
            rectangle.fillColor = 'red'

Thank you for any help on this issue!

Best, M
```

You need to de-indent the `else` - currently you’re saying “if the fill colour is red, make it white, and if it’s not red, make it red”
