On the pattern supply list, the recommend white aida, so the green is stitched. A black and white symbol pattern means the printout of the pattern is white blocks with black symbols in the grid. A color pattern looks more like a pixelated picture with the symbols ontop of the colored box. I hope that makes sense.

Noah is correct that the pattern is 100% stitching (coverall). If you want, you can save stitching by using light gray or green fabric or a dyed/marbleized fabric, which I think would be very pretty. IF you order this lovely pattern don't be surprised that is has a lot of pages. More pages allow for a larger grid making the pattern easier to follow.
