Is there a way to change the color of the directional thread arrows in pattern generator? I would like to use dark colors for the bracelet, but when it is generated the arrows cannot be seen. I would like to be able to change the black arrows to white. Is that possible?

No, that’s not possible. It’s best to not use really dark colors, for example for black use dark gray instead. The arrows are always black, so if you turn up the lighting of your screen you should be able to see the arrows on darker colors though.
But you can also follow the colored lines and see where the color comes from and where it goes after the knot. Then you know what knot it is.
