nightblue

Night blue is a deep blue color that evokes the appearance of a night sky seen through darkness. It is not a single standardized shade; the precise hue labeled "night blue" varies by source and medium. In digital color systems, it is generally a very dark blue, often near blue-black. Common close approximations in design palettes include navy blue (#000080) and midnight blue (#191970). Some references describe even deeper tones, such as hex values around #0A1F44 or #001f3f, to convey nocturnal depth.

Historically, the term arose in textiles and painting to describe rich, dark blues used for formalwear and decorative fabrics. In contemporary usage, night blue appears in fashion, branding, and interior design as a versatile option that communicates seriousness, stability, and sophistication without the starkness of pure black. It can pair well with lighter neutrals, metallics, or bold accent colors.

Perception and accessibility considerations matter when using night blue in design: very dark blues can reduce legibility for light-on-dark text and may shift in appearance under different lighting. Since "night blue" lacks a universal standard, designers typically rely on specific color swatches or industry standards to define the exact shade for a given project.
