What goes with Harvard Slate

Neutral gray is a useful bridge between white trim and mixed masonry. Choose a siding value clearly lighter than the roof to preserve the roofline.

Siding

  • light gray lap siding
  • soft white stucco
  • balanced greige brick
  • natural limestone

Trim

  • soft white
  • graphite
  • light putty

Watch out: Avoid siding and roofing with identical midgray values if you want a distinct outline.
