About Ultramarine (#0B0F99)

The hex color #0B0F99, known as Ultramarine, is a deep shade of blue, characterized by its rich and intense tone. It belongs to the blue color family and carries a sense of depth and sophistication. In the RGB color model, it is composed of 4.31% red, 5.88% green, and 60% blue. Its high blue component gives it its distinctive appearance. Ultramarine historically comes from the pigment derived from the gemstone lapis lazuli, making it a highly valued color. It's often associated with royalty, wisdom, and tranquility. Its color properties give a certain mood to designs and artwork, and it is important to consider these factors while designing with the color.

The hex color #0B0F99, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low lightness value of approximately 6% means that text rendered in this color on a white or light-colored background will have very poor contrast. This violates WCAG (Web Content Accessibility Guidelines) standards, which require a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. To improve accessibility, consider using #0B0F99 sparingly, and always ensure sufficient contrast with the background. A lighter text color, such as white or a very pale yellow, would be necessary to meet accessibility standards. Tools like contrast checkers can help verify compliance.
