The main difference between Off Black and Jet Black is brightness and saturation: both are near-black shades, but Off Black is lighter. Off Black and Jet Black are often confused but have distinct differences in hue, saturation, and tone. Off Black (#1C1C1C) and Jet Black (#0A0A0A) each suit different design contexts — understanding their differences helps you choose the right color for your project.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Off Black is more saturated (0% HSL vs 0%) so it reads as bolder and more memorable at logo scale, while Jet Black can feel washed out when printed small.
Jet Black hits a 19.80:1 WCAG contrast against white — safer for text-heavy interfaces — where Off Black only reaches 17.04:1 and risks failing AA at small body sizes.
Off Black is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Jet Black leans cooler and is better suited to autumn/winter layering.
Off Black is the more muted of the two (0% saturation) and sits more calmly on large wall surfaces, while Jet Black's higher chroma can overwhelm a room when used beyond accent pieces.
Off Black (#1C1C1C) is a very dark, near-neutral near-black with a neutral undertone — it feels deep, heavy, grounded and desaturated and restrained.
Jet Black (#0A0A0A) is a very dark, near-neutral near-black with a neutral undertone — it feels deep, heavy, grounded and desaturated and restrained.
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.
