|Hundreds of books are available on watercolor painting and art techniques. I don't know where your artistic path will lead, but I have reviewed the books that impressed me as remarkable ... good or bad. Many of the books present the same material in a very similar way; I try to identify what is unique to each. (The title of each book links to the ordering page for the book on amazon.com.)
A caution on the use of artist books and magazines: they are, after all, in a business.
learning the basics
Books that provide a complete course of watercolor study: brushes, paints, papers, color theory, basic brush technique, and painting projects of easy to intermediate difficulty.
pigments, paints & papers
It's important to choose your painting materials carefully. These books provide information on the many watercolor paints and papers, with background information on their manufacture.
color science & "color theory"
Color from all angles: the history of color in art, color vision, classic books on color (including Chevreul and Goethe, practical guides to color mixing, color design, and color in contemporary art.
These books do not go very far into the basic painting materials or specific painting skills, but instead emphasize good design principles, the philosophy of art, and nurturing your own creativity.
how-to by subject
Tutorials in watercolor painting focused on specific genres (florals, portraits, landscapes), specific styles, or specific techniques (textures, masking).
Comprehensive reference works that provide a wider understanding of painting materials, methods, and related art topics.
