As part of the quiz
Is there a way to highlight only a certain number of strokes?

Is the idea that you want to quiz the user on only a subset of the strokes in the character? I don't understand what the picture means. There's 1 stroke drawn in black in the picture. Is this stroke something the user just drew, or is this stroke always shown in black during the quiz? I'm not sure I understand what you're trying to do

It's a quiz to guess the order of the black strokes.

example images, the correct answer is 4.
