#0A092B

General Information about #0A092B

The hex color #0A092B, often referred to as "Black Rock," is a very dark shade that sits firmly within the realm of deep indigo hues. It is composed of a small amount of red (0A), green (09), and a more significant portion of blue (2B), creating its distinct dark tone. In the RGB color model, this translates to approximately 4% red, 3.5% green, and 17.3% blue. This color is often associated with sophistication, mystery, and depth. Given its darkness, it's important to consider its use carefully in design to ensure readability and accessibility. In contexts like web design, it's crucial to pair it with lighter, contrasting colors for text and interactive elements. Black Rock can also be seen in various forms of art and fashion, often to convey a sense of elegance and power.

The hex color #0A092B, also known as Black Rock, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of approximately 0.002 makes it a very dark color, resulting in poor contrast against most backgrounds, including white. According to WCAG (Web Content Accessibility Guidelines) standards, sufficient contrast between text and background is crucial for readability. To ensure accessibility, using #0A092B for text requires a very light foreground color, and even then, careful consideration is needed to meet minimum contrast ratios. For instance, a white text (#FFFFFF) on a #0A092B background would need to be evaluated using contrast checking tools to verify compliance. Alternatives to using this color for text include reserving it for decorative elements or large graphical elements where the contrast requirement is less stringent. Always prioritize users' ability to perceive and interact with the content effectively. Using this color as a background should also be approached carefully.
