Query: Please add color !!

I just received this book, and although the content does meet my expectations, I must say that some figures are of disappointing poor quality (3D protein representation for instance). I haven't seen the original German version, but it looks as if the English (American) editor has saved a few bucks by simply copying the figures on a B&W copy machine. This is outrageous ! We are living in the 21st century, and any 10 years old computer geek is capable of producing high quality color figures with a decent scanner ! Given the price (70 dollars !), I can't give more that 2 stars !
