Here are some of the the books from my book shelf which focus on color:
Color: a course in mastering the art of mixing colors by Betty Edwards
Remember Drawing on the Right Side of the Brain? The author of this easy-to-follow color theory book is that Betty Edwards.
I bought this book because I had found Drawing on the Right Side of the Brain very helpful for improving my drawing, and reasoned that Color would do the same for my color sense. I also received a high recommendation from my sister, who worked through all the exercises.
Color choices: making color sense out of color theory by Stephen Quilller.
Stephen Quiller talks about being on the quest of becoming a better artist. To do this, he not only keeps his eyes and mind open to the world around him for subject matter, but studies other artists whom he admires.
One of his favorite pastimes is to go to art museums and galleries, and learn from others how he can improve his own painting. At home, he continues to research artists from a large personal collection of art books, and books he borrows from public libraries. As Stephen puts it:
I find it helpful to soak in all I can of each artist; many times it inspires me in my painting. This does not mean copying the masters’ works. it simply means that when I absorb the work of great artists, their painting will help me see my own work better. It will help me see how key lines in my composition can be changed, color combinations improved, or line quality altered to better the statement. In researching these artists, I have found that they all have had one thing in common.They were all students throughout their lives.
I love the way Stephen Quiller uses color, and bought this book so that I could study him. I was also intrigued with his Quiller Color Wheel, which was missing in the library copy I borrowed.
There are other Quiller books available, by the way, and DVDs.
