In the RGB color model, it consists of 3.92% red, 5.1% green, and 18.43% blue. This composition results in a color that is perceived as deep, mysterious, and almost black. Due to its darkness, it absorbs a significant amount of light, making it a challenging color to work with in design, especially regarding accessibility. It is often used to convey sophistication, elegance, and a sense of depth in various applications, ranging from web design to interior decorating.

The hex color #0A0D2F, also known as Black Rock, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value makes it difficult to distinguish from pure black, leading to poor contrast when used as a text or background color. According to WCAG guidelines, sufficient contrast is crucial for readability. To ensure accessibility, avoid using #0A0D2F for text or interactive elements unless paired with a very light color that provides a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Consider using color contrast checkers to verify compliance. Furthermore, provide alternative visual cues, such as icons or text labels, to supplement color-based information. It is generally advisable to use this color sparingly in user interfaces to prevent eye strain and ensure a positive user experience for everyone, especially those with disabilities.
