Ultramarine historically was derived from the precious stone lapis lazuli, making it a highly valued pigment. It is often associated with royalty, depth, and intelligence. In color psychology, blues are often linked to trust, stability, and peace. This makes Ultramarine a great choice for brands looking to convey reliability and authority. However, it can also be perceived as cold or distant, so it should be used judiciously.

The color #1B0FA5, also known as Ultramarine, presents several accessibility considerations for web developers. Its deep, saturated hue results in low luminance, potentially causing issues for users with visual impairments. When used as text, a very light color like white or a pale yellow should be used as foreground. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG guidelines. If used for interactive elements like buttons or links, ensure sufficient visual cues beyond color alone are present to aid users who may be colorblind. Consider adding borders, icons, or text labels to enhance usability. Avoid using this color as the sole indicator for important information or actions.
