Great Book

I have added a great new book to my bulging art book cases.  This one is not for everyone.  Its not a how to book, or a color mixing book, or a color theory book.  It is a book that details different tubes of paint colors and how they vary from manufacturer to manufacturer.  As an artist of very limited means, I am constantly frustrated by the inconsistencies of pigment colors from one brand to the other.  One brand of yellow ochre, for example, can range from chalky yellow brown to vibrant creamy yellow to orange brown to rust!  This book shows color swatches by color families of several manufacturers side by side.  It will help me in deciding which $30 tube of paint I want to invest in.   Now, don't get me wrong.  Give me a warm and cool blue, red and yellow and white and I can mix any color I need. (unless its neon or metallics). It's a skill that has taken me years to master, but I am at the stage with my painting where I want some time shortcuts, dang it!  And spending hundreds of dollars to play with brands is not an option.
