General Information About Black Rock

The hexadecimal color code #100B2A, also known as Black Rock, represents a dark shade of blue tending towards black. In the RGB color model, it is composed of 6.27% red, 4.31% green, and 16.47% blue. This color is often associated with feelings of sophistication, mystery, and depth. In color theory, #100B2A can be used to create contrast when paired with lighter shades or to evoke a sense of calmness and serenity when combined with similar dark tones. Its dark nature implies that it has a relatively low luminance value. The name 'Black Rock' suggests a connection to natural elements, adding to its appeal in design contexts aiming for an organic or grounded aesthetic. When using this color, consider its impact on readability and ensure that sufficient contrast is provided for any text or interactive elements.

The hex color #100B2A, also known as Black Rock, presents some accessibility challenges, particularly when used as a background color for text. Due to its low luminance, the contrast ratio against standard white text (or lighter colors) is likely to be insufficient to meet WCAG (Web Content Accessibility Guidelines) requirements for levels AA and AAA. This means that users with visual impairments, such as those with low vision or color blindness, may struggle to read text displayed against this background. To improve accessibility, consider pairing #100B2A with much lighter text colors like whites or very light grays to ensure sufficient contrast. Alternatively, #100B2A can be used for decorative elements where readability is not critical. When used in combination with interactive elements, such as buttons or links, attention must be paid to hover, focus, and active states to ensure that these states have sufficient contrast ratios. Testing with accessibility tools is highly recommended.
