#0A0B21

General Information about Ebony (#0A0B21)

The hex color #0A0B21, often referred to as Ebony, is a very dark shade of blue-gray. It resides in the lower end of the color spectrum, possessing minimal brightness and saturation. Its RGB values are R:10, G:11, and B:33, indicating a significantly higher blue component compared to red and green, contributing to its subtle bluish undertone. In the context of color theory, Ebony is considered a neutral color, suitable for creating backgrounds or providing a base for more vibrant colors. However, its darkness makes it challenging to use directly for text or interface elements without careful consideration of contrast ratios. Ebony, due to its association with the dark hardwood of the same name, evokes feelings of sophistication, luxury, and mystery. It can add a touch of elegance and drama to designs when implemented thoughtfully.

The hex color #0A0B21, also known as Ebony, presents significant accessibility challenges, especially in text-based applications. Its extremely low luminance value results in very poor contrast against almost any background color, including white. This lack of contrast makes it difficult for users, particularly those with visual impairments, to read text or distinguish interface elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ebony falls far short of these recommendations, necessitating careful consideration of its use. To improve accessibility, it's crucial to pair Ebony with very light colors or avoid using it for text altogether. For decorative purposes where legibility is not paramount, it can be employed more freely, but always with an awareness of its limitations regarding visual accessibility. Providing alternative high-contrast themes is also beneficial.
