Ultramarine historically refers to a pigment derived from lapis lazuli, a rare and expensive gemstone, which explains its association with luxury and high art.

In color psychology, it is also associated with introspection and focus.

The hex color #090A8F, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its extremely dark hue results in very low contrast against a standard white background, making text and other elements difficult to read for users with visual impairments. According to WCAG guidelines, this color combination would fail most contrast ratio tests. To improve accessibility, it is essential to pair this color with much lighter shades for text or interactive elements. Consider using tints of white or very pale yellows to ensure readability. Avoid using this color for crucial visual information without sufficient contrast. Thoughtful application of color contrast checkers during design is crucial when incorporating such a deep shade into a user interface to comply with accessibility standards and provide an inclusive experience.
