Question regarding PHP Pro. I've been a long time fan of your books and have over 10 of them plus as many e-books in my library.

I recently purchased PHP Pro and it's the first of your printed books that is not in full color. Was there a color version and a black and white version and I missed the prompt or is this a new thing going forward? I really enjoyed the color, it made the books more enjoyable and engaging. I really hope you haven't decided to only publish in black and white... I'd rather the cost of the books go up.
