Variation of materials and colors on facades is permissible, provided the variation enhances the human scale of the buildings, and is used to define specific elements of the building. General guidelines for variations in materials are:
   (A)   A maximum of three colors, excluding the natural color of brick or stone, may be used on a single structure, except in the case where the building's facade is designed to appear as more than one building. In such case, each element may use a combination of colors as approved by the Landmarks Commission, but the overall color scheme of the building should be coordinated.
   (B)   Changes in materials should occur at inside corners of buildings or transition with an appropriate trim detail. Material changes at outside corners or in the middle of a wall give an impression of thinness and artificiality which should be avoided.
   (C)   The use of a coordinating trim material is encouraged on all facades of a building, and should be used to break larger wall planes into smaller, more human-scale elements.
   (D)   The number of materials on the exterior of a building should be limited to a few complementary materials.
   (E)   A palette of proposed materials and colors should be submitted by the applicant for approval by the Landmarks Commission.
