As a paint with metallic pigments, Neptunus Blue reflects light differently than standard colours. The colour sits in the deep blue range.

The primer choice affects how Neptunus Blue reads. Over black the metallic appears deeper and richer.
Neptunus Blue is a true metallic — the flakes do the work of simulating reflections.
Edge highlights on Neptunus Blue must contrast with the metallic base.
Metallic paints can tarnish over time. Neptunus Blue may need a varnish seal.
