In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, it is composed of 98% cyan, 99% magenta, 0% yellow, and 21% black. This indicates that the color is heavily weighted towards cyan and magenta, resulting in its deep blue appearance. The lightness value of #0401C9 is extremely low, making it appear almost black. Colors similar to #0401C9 are often associated with depth, stability, and authority. However, its very low luminance means it should be used carefully in design to ensure readability and accessibility, especially for text and interactive elements.

The hex color #0401C9, a dark blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of 0.002 makes it difficult to achieve sufficient contrast against lighter backgrounds. According to WCAG (Web Content Accessibility Guidelines), a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Using #0401C9 for text or interactive elements against a white or light-colored background will almost certainly fail these contrast requirements, making content unreadable for many users. To improve accessibility, consider using #0401C9 sparingly and only with very light backgrounds or as a decorative element and always ensure sufficient contrast by pairing it with a very light shade. Another option is to use a lighter shade of blue, such as #6699CC, that provides better contrast.
