In the RGB color model, Cobalt is composed of 0% red, 25.9% green, and 70.2% blue.

Its strong presence and association with positive attributes make it a valuable color in a designer's palette.

The color #0042B3, also known as Cobalt, presents some accessibility challenges, especially for users with visual impairments. Its low luminance value (relatively dark) means that it requires high contrast with text or other foreground elements to ensure readability. A light color, such as white (#FFFFFF) or a very pale yellow (#FFFFE0), is recommended for text on a Cobalt background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. It's crucial to avoid using Cobalt as a background color with dark text, as this can make the content difficult or impossible to read for many users. When using this color, consider employing tools to verify contrast ratios, aiming for a minimum contrast ratio of 4.5:1 for regular text and 3:1 for large text, to ensure compliance with accessibility standards and provide a better user experience for everyone, including those with visual impairments. Also, consider providing alternative color schemes for users who have specific visual needs.
