Understanding its composition helps designers effectively incorporate it into their projects, considering its visual impact and potential limitations.

The hex color #0A0134, also known as Black Rock, presents significant accessibility challenges, primarily due to its extremely dark nature. Its low luminance results in very poor contrast against typical light-colored backgrounds like white or light gray. This makes it difficult for users with visual impairments, including those with low vision or color blindness, to distinguish text or graphical elements rendered in this color. Adhering to WCAG (Web Content Accessibility Guidelines) is crucial. To meet accessibility standards, developers must ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text against the background color. Using #0A0134 as a text color requires a very light background color to achieve sufficient contrast. Additionally, avoid using this color to convey crucial information without providing alternative visual cues, such as icons or text labels, to ensure usability for all users.
