Hi,
I don't understand why the hatching of the two rectangles is not the same
color.
Thanks for your help.

To see this, replace your lines with : draw q anglestriped (1,45,2) withcolor cyan; draw b anglestriped (1,45,2) withcolor red; And you will see that the path b is drawn twice : once in red, once in cyan. So if you change your instructions to : draw q anglestriped (1,45,2) withcolor cyan; draw r anglestriped (1,45,2) withcolor cyan; This will correct the problem, because each path is now drawn only once.
