#05052F, also known as Black Rock, is a very dark shade of blue that belongs to the blue color family. In the RGB color model, it is composed of 2% red, 2% green, and 18% blue. In the CMYK color model, used in printing, it consists of 89% cyan, 89% magenta, 0% yellow, and 82% black. This color is often associated with depth, mystery, and sophistication. Due to its very low lightness value, it reflects very little light and appears almost black to the human eye. When used in design, it is crucial to pair it with much lighter colors to provide sufficient contrast and ensure readability.

The hex color #05052F, a very dark shade of blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value 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. Using #05052F without careful consideration of contrast could result in content that is unreadable or difficult to perceive. Designers should prioritize providing high contrast color combinations to meet accessibility standards and ensure inclusivity for all users. Tools like contrast checkers can be used to verify that color choices meet the necessary contrast ratios.
