This book is a pragmatic guide to almost every issue relating to designing effective visualizations along with explanations of the whys and wherefores based on human perception. Sprinkled thru-out are concise guidelines - many of which are mentioned below.
While I have worked in computer graphics technology for 25 years (or 30 if you count the TTY plotter I did in high school) and I have designed and implemented a few UIs and debugged a few more, I do not consider myself a pro. So, I will claim that this book would be fascinating to anyone who knows what RGB stands for and is seriously curious about the human perception system.
The book zigs and zags from physics to screen appearance to neurons to colors to the visual cortex to the implications for good design. While I have been working on various aspects of human visual system, Colin Ware's book serves as a wonderful introduction to human visual perception because it is so grounded in its motivation.
What follows is not an attempt to capture or summarize the book, but, my own selfish attempt to make some of this stuff available so I can remember it while I'm at SIGGRAPH.
The section on color is robust - if you want more than this look to Maureen Stone's Field Guide to Digital Color.
Pragmatic guide to color choice (p.140) with these things to consider: color blindness; create ranges using color opponents - black-white, yellow-blue, red-green;
for high levels of detail, use luminance; etc,

Web sites unrelated to the book: Visual Physiology has some good descriptions with mediocre pictures. The Visual System I is a course outline page that has the same schematic map of the visual cortex that is in The Blank Slate
I started The Cognitive Neuroscience of Vision by Martha J Farah. That book desperately needs some diagrams. It is written for experts in the field and is extremely dense, but, that just means it is slow going for us lay folk. So slow going that I put it down for a while.
You can use pre-attentive processing to cue the visual system to queue up certain graphical elements such that when the conscious attention does move to it, it is already recognized.
p. 203 Gestalt Laws from 1912. Gestalt is German for pattern. School of Psychology produced a set of laws for pattern perception. They describe proximity, similarity, continuity, symmetry, closure, relative size, and figure/ground.
On Page 225 are even more guidelines for diagrams. #1 closed contour for objects... #13 proximity for groups. Perhaps common sense... that comes with lots of experience.
glyph design using spatial, color, shape, orientation, texture, motion & blink. p.195
different depth cues (perspective, depth cue (fog), stereo...) work better and worse depending on the task! p.297 interesting!!!
images vs. words (p. 320) structure better visualized, abstractions better verbalized + many, many more guidelines. In the section on Word & Images - when to use which, there is a bit on brain regions and fMRI and verbal and visual processing.
Note: definition of contrast p.61: (Lmax - Lmin)/(Lmax+Lmin)
