Hi vincentn20,

Can you please format.  
Check out this thread to know how to do it: [Guidelines—Tips on Asking Questions](https://discourse.processing.org/t/guidelines-tips-on-asking-questions/2147)

Now for your question, I advise you do go have a look to the [mouseClicked()](https://processing.org/reference/mouseClicked_.html) function and the [lerpColor()](https://processing.org/reference/lerpColor_.html) one.

Also I can’t see how your code can work, you miss the basic structure of a processing program.
