MediumBlue

MediumBlue is a named color used in web design and defined in the CSS color vocabulary. It corresponds to the hex value #0000CD, with RGB components 0, 0, 205. In HSL terms, it is near 240 degrees hue, 100% saturation, and about 40% lightness, placing it as a mid-range blue that is noticeably deeper than primary blues but not as dark as navy.

As part of the CSS named colors, MediumBlue is a standard, widely supported color across modern web browsers and operating systems. The color name is case-insensitive in CSS and HTML, and it can be specified in style sheets or inline styles along with other color values.

In design practice, MediumBlue is often used for links, accents, and user interface elements where a calm but distinct blue is desired. It conveys reliability and professionalism and pairs well with lighter backgrounds and neutral tones. It is less saturated than some brighter blues, which can aid readability in certain layouts.

Accessibility considerations include ensuring sufficient contrast with the chosen background. For body text, contrast against light backgrounds should meet WCAG guidelines, typically requiring a minimum ratio of 4.5:1 for normal text. On dark backgrounds, MediumBlue can be effective, but readability should be verified with contrast checking tools for the specific font size and weight used.
