Query: Needs color pictures

The book itself has some decent info, but the B&W pictures kill the whole effort. Many of the pictures are just unclear, and the majority fail to convey useful visual information. I mean we are talking about plants here! If you can't see the colors, you're missing quite a lot! I am really surprised they would publish this without color pictures. Cost-cutting gone awry!
