web pics:
planks --- obviously the colors are all over the map on this but I have no idea whether it's because there are numerous species sold under the same name and thus some/all of the variation is real, or if it's a matter of poor color correction, or if it's a matter of mis-identification, or more likely, some combination of the three.
