This significant dominance of blue gives the color its distinctive hue. The color is often associated with depth, stability, and authority. Due to its dark nature, it has a low luminance value, which impacts its usability in various applications, particularly in contexts where readability and contrast are essential. Understanding the RGB composition and luminance value is crucial for designers and developers when incorporating this color into their projects, ensuring it aligns with aesthetic goals and accessibility requirements.

The color #0405B0, a dark blue, presents significant accessibility challenges, primarily due to its low luminance. When used as text, it requires a very light background to achieve sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This dark blue shade will likely fail these criteria against many common background colors. To improve accessibility, consider using a lighter tint of blue or pairing it with a much lighter color. Using this color for purely decorative elements is acceptable if it does not convey essential information. Also, avoid using it for interactive elements without clear visual cues beyond color, such as underlines for links or icons with labels for buttons. Always test the color combination with accessibility evaluation tools to ensure compliance with accessibility standards and provide an inclusive user experience.
