I’m guessing it wants you to fill in two major key signatures like D major and C major also with two minor key signatures like A minor and B minor. I picked those key signatures because A minor is the same as C major but it starts on A and D major and B minor is the same but it starts on B
flats: Bflat Eflat Aflat
scale: Eflat F G Aflat Bflat C D Eflat
I would say a flesh color; that’s what’s safest. If you feel daring, then a red or black.
Trying to find all of the small, and different pieces that would fit together in a beautiful way.
