General Information about #0A033A

The hex color #0A033A, also referred to as Black Rock, is a very dark shade of blue-purple. In the RGB color model, it is composed of 3.92% red, 1.18% green, and 22.75% blue. This composition results in a color that leans heavily towards the blue end of the spectrum, with minimal contributions from red and green. The color's darkness is due to the low values across all three channels. It's often perceived as mysterious and sophisticated, reminiscent of deep ocean depths or a night sky. Colors like these can be used to set the tone for many applications, if done correctly. Black Rock provides designers with a canvas to create impactful projects.

The hex color #0A033A, also known as Black Rock, presents significant accessibility challenges, primarily due to its very dark nature. When used as a foreground color for text, it necessitates a very light background color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Using #0A033A on a dark or moderately dark background would render the text nearly invisible, posing a major barrier for users, especially those with visual impairments. Therefore, it is crucial to pair this color with a significantly lighter hue to meet accessibility standards and provide a positive user experience. Always test color combinations with accessibility tools to confirm adequate contrast.
