General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #000198, is a deep, intense shade of blue. It is named after the pigment derived from the mineral lapis lazuli, a semi-precious stone prized for its rich color since antiquity. This color is characterized by its high saturation and low luminance, making it a very dark hue. In the RGB color model, #000198 is composed of 0% red, 0.39% green, and 59.61% blue. In the CMYK color model, it consists of 100% cyan, 99.6% magenta, 0% yellow, and 40.39% black. This color is often associated with depth, stability, and trust, making it a popular choice for branding and design where these qualities are desired. Due to its darkness, Ultramarine should be used carefully in applications where readability and accessibility are important.

The hex color #000198, a very dark shade of blue also known as Ultramarine, presents significant accessibility challenges, especially when used for text or interactive elements. Due to its extremely low luminance, it creates insufficient contrast against light backgrounds, making it difficult for users with visual impairments to read or interact with the content. The Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Ultramarine typically fails to meet these standards against common background colors like white or light gray. Therefore, it is crucial to pair this color with much lighter shades to ensure readability and usability. Implementing techniques such as color contrast analyzers can help determine whether the color combination meets accessibility standards. Designers and developers must prioritize accessibility to provide an inclusive experience for all users, including those with low vision or color blindness.
