Reception decor

I need help. My reception table cloths and chair covers are white. I am going to do chair sashes and have my sweetheart table and cake table have matching specialty cloths. My floral arrangements are shades of white, ivory, cream, beiges. My overall colors are silver, white,ivory,taupe and hints of black. How would you use these colors. I’m not sure of the color napkins, sashes, specialty cloths, runners and how to incorporate it all so it makes sense and ties together.
