Ultramarine historically derives from the pigment extracted from the semi-precious stone lapis lazuli, making it a highly prized and expensive pigment in the past.

In color psychology, Ultramarine is often associated with depth, stability, and wisdom, making it a popular choice for branding and designs that aim to convey these qualities.

The color #150394, a deep Ultramarine, presents significant accessibility challenges. Its low luminance of approximately 3% makes it difficult to read text rendered in this color against a standard white background. To meet WCAG (Web Content Accessibility Guidelines) standards, especially AA and AAA levels, it's crucial to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. This often necessitates pairing #150394 with very light colors, such as shades of white or pale yellow. When using this color for interactive elements like buttons or links, sufficient visual cues beyond just color should be provided to aid users with color vision deficiencies. Avoid using it for essential information without strong contrast, and consider providing alternative high-contrast themes for users who require them. Proper accessibility considerations ensure a more inclusive and user-friendly experience for all users.
