"Sketch" and many of the other filters use the foreground and background colors — they don't have to be B&W. We didn't see original colors, but it looked like they were both very pale. The filter worked correctly, but you didn't like it. (Neither did I!)
Experiment with other colors. Try blue & white or green & yellow to see what happens, then choose two colors that work for you.
If you have a Smart Object and are working non-destructively, you can delete the filter. If you don't have a Smart Object and are working destructively, choose Undo after each experiment.
