In the RGB (Red, Green, Blue) color model, #0100B4 is composed of 0.4% red, 0% green, and 70.6% blue. This significant dominance of blue gives the color its characteristic deep blue hue. The color is mostly known as "Dark Blue". Hexadecimal color codes are widely used in web design and digital graphics to precisely define colors. In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, it translates to approximately 99% cyan, 100% magenta, 0% yellow, and 29% black. Understanding these color models allows designers to accurately reproduce and manipulate colors across different media.

The color #0100B4, a deep dark blue, presents several accessibility considerations for web design. Due to its low luminance, it necessitates careful pairing with contrasting colors to ensure readability. Text rendered in #0100B4 on a similarly dark background would be virtually illegible for most users, and problematic even on mid-tone backgrounds. A high contrast ratio, ideally exceeding 4.5:1 for normal text and 3:1 for large text, is crucial according to WCAG guidelines. White or very light shades of yellow or green are recommended for text or interface elements layered on #0100B4. Additionally, avoid using this color as the sole indicator for interactive elements like links or buttons; supplement it with other visual cues like underlines or borders to accommodate users with color vision deficiencies. Thorough testing with accessibility evaluation tools is essential to guarantee compliance and usability for all users.
