Deep Blue

#003087

Quality 0.94

Deep Blue is a cool, deep blue with a semi-gloss finish, identified by HEX #003087. It is most effective in joinery, studies, front doors, and feature walls where a calm and clear look is preferred over a bold statement. This colour can shift noticeably between daylight, warm lamps, and surrounding materials, so it's important to sample it next to trims, flooring, cabinetry, and fabrics before applying it to a full room. Begin with a restrained palette, introducing a stronger secondary accent only if the sample seems flat.

Quick guidance

This is a deep tone. It works best as an accent, joinery colour, or feature wall.

Where Deep Blue works best

Deep Blue is most reliable on joinery, studies, front doors, and feature walls. For larger areas, ensure there is enough natural light or lighter surrounding materials to prevent the room from feeling enclosed. If uncertain, start with a single wall, joinery face, robe interior, or vanity, and observe it in various lighting conditions before expanding its use.

Pairing and contrast advice

White or very light detailing provides clearer contrast against Deep Blue, with a contrast ratio of 11.85:1 against white. It pairs well with crisp whites, pale timbers, limestone, brushed nickel, and charcoal accents. Without linked style profiles, keep the initial palette simple and let materials enhance the visual impact.

Finish notes

The semi-gloss finish of Deep Blue enhances its vividness by reflecting light, which sharpens edges and surface variations. This effect is beneficial on trim, doors, and feature joinery, but requires high-quality preparation. On large wall areas, the finish can feel busy unless balanced with a restrained palette.

Frequently asked questions

What rooms does Deep Blue usually suit best?

Deep Blue is ideal for joinery, studies, front doors, and feature walls. Its suitability depends on natural light, room size, and surrounding materials, so it's crucial to test it in the actual space rather than relying solely on a digital swatch.

What colours and materials pair well with Deep Blue?

Deep Blue pairs best with crisp whites, pale timbers, limestone, brushed nickel, and charcoal accents. Begin with adjacent neutrals, then add a stronger accent only after the sample feels well-integrated in the room.

Should Deep Blue be used with dark or light trim and text?

White or very light detailing provides better contrast with Deep Blue than black. Despite contrast calculations, test it next to your trim colour and hardware, as sheen, texture, and room lighting can alter the final appearance.
