Every figure a contractor or an insurer will ask about, with the standard it is measured against.
What you're looking at.
The granule tones the blend is built from, how the colour is classified, and how it behaves on a roof.
Harbor Blue is the cool-end specialty in the Duration catalog. It is a confident, slightly slate-leaning blue that pairs naturally with coastal whites, sage, and natural wood. Specified far less often than gray or brown, but unbeatable on the right elevation.
The granule blend uses a base of slate-blue with smaller portions of charcoal and storm-gray to keep the cool tone honest. Up close you can see the layering; from the street it collapses into one quiet blue plane.
Pairs naturally with cool whites, light sage, soft natural wood, and crisp navy accents. Pairs poorly with warm yellows, terracotta, or red brick where the cool undertone fights.

A confident cool blue with slate and storm-gray granule accents. In direct Florida sun it reads as a clean blue; in shade it pulls toward cool gray. Far less common than gray or brown in the asphalt category, which is part of the appeal.
