This book is about connotative aesthetic principles, which could be summarised as principle of subtle difference of visual elements, and principle of unification of relation elements. The coordination of the visual elements (shape, colour, texture) and the relation elements (massing, image, proportion) is the main constituting element of the spatial design of the city. Principle of subtle difference of visual elements means that when dealing with the unitary architecture among the architectural complex, subtle difference is allowable in shape, color and texture. Meanwhile, this subtle difference should be controlled within a certain range in order to guarantee the visual identity of the complex.
