About #1B00CA

The hexadecimal color code #1B00CA represents a dark shade of blue. In the RGB (Red, Green, Blue) color model, it consists of 10.6% red, 0% green, and 79.2% blue. This indicates a strong dominance of blue, resulting in the characteristic dark blue appearance. Hex color codes are widely used in web design and graphic design for specifying colors in a precise and consistent manner. Understanding the RGB components allows designers to adjust the color's intensity and create variations. The color can be used with different color palettes. Because it is a dark color, it's crucial to consider contrast ratios for accessibility, especially when used for text or interactive elements. Color conversion tools can be used to translate the hex code to other color models like CMYK (Cyan, Magenta, Yellow, Black) for print media.

The hex color #1B00CA, a deep dark blue, presents significant accessibility challenges, especially in text-based contexts. Its low luminance value results in very poor contrast against standard white backgrounds, failing WCAG (Web Content Accessibility Guidelines) AA and AAA standards for text and non-text contrast. This means users with visual impairments, including those with low vision or color blindness, will struggle to read text rendered in this color. To improve accessibility, consider pairing #1B00CA with very light shades of yellow, white, or gray to achieve sufficient contrast ratios. The exact contrast ratio needed depends on the size of the text and the level of compliance targeted. For graphical elements and larger text, a minimum contrast ratio of 3:1 is generally recommended, while body text should aim for at least 4.5:1. Using contrast checking tools is essential to ensure compliance. Avoid using #1B00CA for critical information or interactive elements without careful consideration of contrast.
