General Information about #0400D6
#0400D6 is a dark shade of blue. It has a very low RGB value, indicating it's close to black, thus has a very low luminance. In the RGB color model, it consists of 4/256 parts red, 0/256 parts green, and 214/256 parts blue. This significant bias towards blue gives it its distinct dark blue appearance. In the world of color theory, it falls under the cool color category, often associated with feelings of calmness and sophistication. However, due to its darkness, it can also evoke feelings of melancholy or seriousness. In web design and graphics, careful consideration must be given to its use to ensure readability and accessibility, especially when used as a background color for text or interactive elements. The equivalent CMYK values are approximately Cyan: 100%, Magenta: 100%, Yellow: 0%, Black: 16%.
The color #0400D6, a very dark blue, presents significant accessibility challenges, particularly for users with visual impairments or color vision deficiencies. Its extremely low luminance value means that text or interactive elements rendered in this color would require very light contrasting colors to meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast ratios. A contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text. Using white (#FFFFFF) as the foreground color on a background of #0400D6 would be essential. Without careful consideration of color contrast, content may be unreadable for many users. Providing alternative visual cues, such as icons or text labels, alongside color-coded information can also enhance accessibility. It's also critical to test color combinations with accessibility tools to ensure compliance with accessibility standards. Consider users who may be accessing your site using assistive technologies.
