Hi Fabrice, It seems to me the colors are the same, although they may appear different at first sight because the « with » of the lines are different (the width is larger in the lower rectangle). I attach the PDF created with your code. Best regards: Otared

Hi Otared, It's true that the color seems identical. Thanks. Fabrice Le dim. 19 nov. 2023 à 21:55, Otared Kavian a écrit :

Hi, Fabrice, you have a problem with the definition of the path b: this path include q and b. 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. Fabrice.
