Odeda Rosenthal

I was interested to learn that color-blindness is not solely passed through genetics, but can be an acquired trait (Rosenthal began to research the subject when her husband began to develop color confusion from taking pharmaceuticals). There are many kinds of color vision confusion, the most common being red-green confusion and the most rare being full color blindness (seeing only shades of grey), and this color confusion can confound people in all sorts of ways that people with full color vision don't realize, because color coding has become such a standard in our lives.

I can't say this is the most fascinating book I've ever read. It discusses color vision confusion in a general way, giving an overview of how and why it occurs, a history of research on the subject, examples of how it effects people's lives (many are thought slow or stupid because of it), and some suggestions for how to cope with it. Because I do think that this book is useful as an introductory explanation for people with color blindness who need a way to explain it to others, I'm giving it four stars. If you're reading this book, you probably have color-blindness or know somebody with color-blindness (or are a writer in seek of information, like me), so I wouldn't recommend it for a casual reader.… (mais)
