General Information about #0A0029

The hex color #0A0029, often referred to as "Black Rock", is a very dark shade of blue-black. In the RGB color model, it is composed of 3.92% red, 0% green, and 16.08% blue. This composition gives it a deep, mysterious, and somewhat somber feel. Due to its extremely low luminance, #0A0029 is perceived as being very close to black, which can influence its use in design. It's a color that evokes feelings of sophistication, depth, and even a hint of melancholy. Understanding the composition of this color and its perceptual qualities is crucial for designers looking to incorporate it effectively in various applications.

The hex color #0A0029, also known as Black Rock, presents significant accessibility challenges, especially in web design. Its extremely low luminance value (very close to black) means that text or interactive elements using this color as a background would require very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text to meet AA standards. Using #0A0029 without careful consideration of contrast could render content illegible for users with visual impairments, including those with low vision or color blindness. Therefore, it is highly recommended to pair this color with very light colors, and ideally use a contrast checker to verify compliance with accessibility standards. Overreliance on such a dark color may negatively impact user experience, particularly on screens with poor calibration or in brightly lit environments.
