General Information about #0A0D21

The hex color #0A0D21, often referred to as Ebony, is a very dark shade of blue-black. It belongs to the cool color family and possesses a subtle, muted character. In the RGB color model, it is composed of 3.92% red, 5.1% green, and 12.94% blue. Its primary attribute is its low luminance, rendering it close to pure black. This color is typically associated with sophistication, mystery, and a sense of understated elegance. In color psychology, dark blues can evoke feelings of calmness and stability, though the near-black nature of #0A0D21 mutes these effects. Due to its darkness, it is rarely used as a primary color but is often employed as a background or accent color to provide depth and contrast. It's common in modern minimalist designs to convey a sense of refinement. The perceived color can also vary based on the surrounding colors and lighting conditions.

The hex color #0A0D21 presents significant accessibility challenges, primarily due to its extremely low luminance. When used as a foreground color, it requires a very light background to provide sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for text and interactive elements. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. #0A0D21 would likely fail these criteria against most background colors, necessitating careful selection of a contrasting color. Designers should also consider providing alternative color schemes to enhance accessibility for all users. Testing with accessibility tools is essential to ensure compliance and a positive user experience. Moreover, avoid using this color for critical information or actions without proper contrast. When combined with other dark hues, it further exacerbates accessibility issues. This color is not ideal for complex data visualizations or detailed interfaces where clarity is paramount.
