Cool Gray

Color & finish — Cool Gray

Cool Gray (DND 604) is a soft-steel neutral that balances warm and cool undertones, making it versatile across skin tones. The creamy gel finish provides an even, salon-level sheen that enhances both single-color services and layered nail art. High pigmentation means opaque coverage in fewer coats, giving a smooth, streak-free result.

Benefits for salons & nail pros

This shade speeds up services: richly pigmented formula reduces layering, and its self-leveling texture makes application cleaner and faster. Chip-resistant wear extends client retention between appointments, cutting down on fills and touch-ups. DND 604 is consistent batch-to-batch, so techs can rely on color accuracy for repeat clients and cohesive salon branding.

How to use this gel polish

Apply a thin base coat, cure under LED or UV according to product instructions, then apply 1–2 thin coats of Cool Gray (DND 604) for full opacity—use a third thin coat only if needed. Finish with a gel top coat and cure for durable, high-shine results. Remove with standard soak-off method when needed to protect natural nails.

Why clients will love this shade

Clients appreciate Cool Gray for its understated, modern look that pairs well with work-appropriate and fashion-forward styles. The creamy finish looks polished without being flashy, and durable wear means fewer salon visits between services. Its neutral tone also makes it an excellent base for minimalist decals, chrome, or layered art.
