About Black Rock (#0a0a33)

The hex color #0a0a33, often referred to as 'Black Rock,' is a deep, dark shade of blue-leaning gray.

In the RGB (Red, Green, Blue) color model, it consists of 3.92% red, 3.92% green, and 20% blue. The relatively low values of red and green, combined with a higher blue value, contribute to its unique dark bluish tone. This color is often perceived as sophisticated, mysterious, and understated, making it a versatile choice for various design applications where a subtle yet impactful dark color is desired.

The hex color #0a0a33, also known as Black Rock, presents certain accessibility challenges, particularly in web design. Its dark hue results in low contrast when paired with similarly dark text or background elements. To ensure readability and usability for all users, including those with visual impairments, it's crucial to use sufficiently light text colors, such as white or very light shades of gray. Adhering to WCAG (Web Content Accessibility Guidelines) contrast ratio requirements is highly recommended. A contrast ratio of at least 4.5:1 for regular text and 3:1 for large text is necessary for AA compliance, while AAA compliance requires even higher contrast ratios. Careful consideration of color pairings and the use of contrast checking tools are essential when incorporating #0a0a33 into designs to make content accessible and inclusive.
