I will start this puzzle with a review of my all time favorite book.
This book is about architecture and city planning by authors who worked at a university. Here in the book, there are over 200 chapters. Even though this is a fairly long clue, I won’t discuss all of the chapters.
Parking is considered a problem, and this book has a section in which the author recommends limiting the amount of space given to car parking to 9% of the total land. As cars would be less convenient, they recommend a system of mini-buses instead. The idea of small country towns is seen as important. They can easily fall apart, so must be protected. Everyone considering opening a shop should consider where it is truly necessary, to form a shop web. : Right now, there is a problem, as the authors see it. Neighborhoods are all spread out without boundaries, they need to be more identifiable.
Large and small towns need to be balanced in proper distribution, the authors say. And of course, don’t forget the web of shopping, which also depends on distribution. No subculture should be completely separated or homogenized, thus it should form a mosaic of sorts. Good town distribution contributes to this. Usually, it helps for the subcultures to have a boundary of sorts. Actualizing these plans requires a web of public transportation, so people can get around with ease. Giant cities with no wilderness is no good, in fact, there should be “fingers” of country and city, each less than a mile wide. / Every town needs a ring road, so cars can drive out there without interfering with life inside.
As I was saying before, the authors worked at a university, so they were always thinking about the 9% parking. Lets not forget that they thought big too: one of the theories in the book is that the world must be divided into independent regions. Each region of the world must be independent of the others. X-cept that the regions on a smaller scale (the subcultural boundaries) must be less strict. AND never forget the importance of country towns. (and the ER.)
I figure that’s enough information to get you going. But if this isn’t enough for you, read the book yourself. You might be able to see there what I am talking about here. And don’t say I forgot to tell you what the title of the book is. This puzzle has multiple stages. The first stage's answer will lead you to the second one. The final stage will tell you my favorite color, which is the question this riddle is asking.
If you need a hint to get started, here it is:
The roman emperor was a bit of a shifty fellow. Just take a step forward, because things make much more sense in the present.
You can use wikipedia if you need to...
