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.
Max Def Coastal Blue is the rare asphalt shingle that genuinely reads blue rather than gray-with-a-hint. The granule blend leans cool, with slate and storm-gray accents that keep the surface from looking artificial. On a south-facing Florida elevation in midday sun, the blue tone is unmistakable.
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.
Works best on coastal craftsman, Cape Cod, Nantucket-style, and contemporary builds. Less flexible than gray but more memorable.

About Max Def Coastal Blue.
Questions homeowners ask before they commit. Answered without sales spin.
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.
