发帖数: 14844 | 3 华人的水平就是不行。看看人家true expert是怎么说的：
1. If the paper is Red, one can draw 7 red lines with green ink and
transparent ink.
2. The expert confused others to say that all lines are perpendicular to
each other. The original problem statement didn't say that. Probably they
want the lines to be perpendicular to the paper. One could it as a 3D
illusion of lines protruding perpendicular to the paper, using shadows, etc.
. btw shadows don't need grey ink, just dark green ink :) | p**j
