A light, neutral gray, Castlerock carries minimal undertones and a distinctly restful presence. With an LRV of 67, it creates a calm, cohesive feel in open-concept spaces, hallways, and bedrooms alike. Kilz offers Soft Steel as a near-identical match, while PPG's Flagstone is also very similar. It pairs beautifully with warm wood tones to offset its coolness, or with silver and chrome for a polished look.
