General Information about #0D072E

The hexadecimal color code #0D072E, also known as Black Rock, represents a very dark shade of blue-purple. In the RGB color model, it consists of 5.1% red, 2.7% green, and 18% blue. It sits within the cool end of the color spectrum and carries connotations of depth, mystery, and sophistication. Colors similar to Black Rock are often associated with the night sky or deep ocean waters, evoking a sense of calm and introspection. This specific shade is created by subtly blending red and green into a dominant blue hue, resulting in its unique character. The color depth makes it quite unusual for common use, needing bright accents to balance correctly. It is more common in digital designs than physical applications due to its vibrancy being better expressed on screens. Overall the color is more of a design choice than a utility choice.

The color #0D072E, a very dark shade of blue-purple, presents significant accessibility challenges, especially in web design. Its extremely low luminance value means that text or other interactive elements rendered in this color require careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal-sized text and 3:1 for large text against its background to be considered accessible to users with moderate visual impairments. Due to its darkness, #0D072E typically necessitates very light foreground colors (e.g., white or near-white) to achieve sufficient contrast. Without this, content becomes difficult or impossible for many users to read. Designers should use contrast checking tools to verify compliance and consider providing alternative high-contrast themes to accommodate users' individual needs. Furthermore, avoid using #0D072E for crucial visual information where color is the sole differentiator, as this can exclude users with color vision deficiencies.
