Have you tried [debugging your code](https://happycoding.io/tutorials/processing/debugging)?

Have you checked the value of `javaColor`? Is it non-null? What are its red, green, and blue components? Are they all what you expected?

Try to get something simpler working. Can you write an example sketch that hard-codes a Java `Color` and translates it to a Processing `color`? Then make it so the color is from a color chooser. Work your way forward in small steps like that.
