Web Design for Developers: A Programmer's Guide to Design Tools and Techniques by Brian P. Hogan
Developers don't get to spend a lot of time thinking about design, but many secretly wish they knew how to make their applications look just a little bit better. This book takes you on a journey through a web site redesign, where you'll learn the basic concepts of design, color theory, typography, and accessibility. You'll learn how to take a sketch and transform it into a digital mockup in Photoshop, and then finally into a working web page. You'll see how to develop logos, icons, and buttons using Illustrator and Photoshop, and then code a web page that will load fast, be easy to maintain, and most of all, be accessible to all audiences.
