question:
Review: I have only read the first 44 pages of this book, so I'd need to read the rest. So far, though, it is interesting but seems fuzzy. The writer makes a lot of claims but I was rarely sure if they were proven or just speculation. This is the kind of sentence that makes me queasy:"Given all the activations happening at once [in the brain], physical performance probably uses 100 precent of the brain" (p. 39).Probably? Why? Does any one activity use 100 percent of the brain? And if physical performance does, why is that important? 
 Polarity: Negative
answer:
True

False


question:
Review: Itten's analysis and application of color is thoughtful and scientific. As a practicing art director, I have successfully used the theories and methods explained in "Elements of Color" for over twenty years. I also teach them to my design classes. Whether you use a paintbrush or a mouse, his "seven color contrasts" will prove invaluable. 
 Polarity: Negative
