The main difference between Navy and Midnight Blue is brightness and saturation: both are purple shades, but they share similar brightness and Navy is more saturated. Navy (#000080) is a pure dark blue, while Midnight Blue (#191970) is a slightly lighter dark blue with a purple undertone. Navy is pure blue at half intensity; midnight blue adds a small amount of red, tilting toward indigo.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Navy is more saturated (100% HSL vs 64%) so it reads as bolder and more memorable at logo scale, while Midnight Blue can feel washed out when printed small.
Navy hits a 16.01:1 WCAG contrast against white — safer for text-heavy interfaces — where Midnight Blue only reaches 14.85:1 and risks failing AA at small body sizes.
Midnight Blue is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Navy leans cooler and is better suited to autumn/winter layering.
Midnight Blue is the more muted of the two (64% saturation) and sits more calmly on large wall surfaces, while Navy's higher chroma can overwhelm a room when used beyond accent pieces.
Navy (RGB 0,0,128) is a pure dark blue with zero red and zero green content — the original British Royal Navy uniform color, formalized in 1748.
Midnight Blue (RGB 25,25,112) is a dark blue-indigo with small but equal red and green components, pulling the hue slightly toward purple. Named after the color of a cloudless night sky.
Text legibility depends on the contrast ratio between foreground and background. WCAG 2.1 AA requires at least 4.5:1 for normal text and 3:1 for large text; AAA requires 7:1. Use these numbers to choose accessible combinations for your design.
