Revit API Design Intent

Once the models were complete, I wanted to use Revit API to randomize the colors of the exterior curtain panels on the flat faces of the building and the corner void faces of the building independently. I believe the building appeal is in the uniformity of the exterior truss system and how its symmetry and solid colors help a person’s eye flow from the bottom of the tower to the top. Any discrepancies in the color scheme would distort the view flow and take away from the overall appeal of the truss system and its skin. So with Revit API, I will be randomizing the colors of the two different locations of curtain panels in the Revit Model so that the skin of the building will keep its consistency within flat faces of the building and the corners will contrast more from those flat faces to show more of the geometric shape of the structure.
