Seerblue,

I'm trying to figure out how to transform a greyscale color to a greyscale range so that the lightest color of the lower polygon ends where the darkest color of upper polygon begins in Illustrator. You see, all i did for contour lines is to draw smaller and smaller polygons on top of each other. The lower polygon doesn't stop where the upper one begins, it's just below the upper one. If i fill my polygons woth greyscale range, the lighter colors will just be below the other. It will not end at their frontier. I don't know how to make it end at their frontier.

As you can see, i'm also really bad at explaining. English not being my native tongue.

Can you make something of what i just said?
