RE: Recommendation for graphical app. for doing color schemes?
All right, I'll explain what I would do on CS-2, I don't know if the procedure on Elements is the same, but must be very alike
1.- Trace your first line
2.- Trace your second line
3.- Using the marquee or poligonal lasso tool, trace an area where you want your filling
4.- Create a new layer (without deselecting)
5.- Use the paint bucket to fill the selected area
