The color #100A2B, also known as Black Rock, presents significant accessibility challenges, especially for users with visual impairments. Its very low luminance results in poor contrast against almost any background color. When used as text, it would be nearly unreadable for many individuals. To ensure accessibility, it's crucial to avoid using this color for text or important interface elements unless paired with a very light color that provides a high contrast ratio (at least 4.5:1 for normal text and 3:1 for large text). Consider using color contrast checkers to verify the contrast ratio. Also, provide alternative cues like icons or text labels to convey information, rather than relying solely on color. Providing high contrast is very important for people viewing a screen in bright sunlight.
