Ultramarine has a historical significance, originating from the pigment derived from the semi-precious stone lapis lazuli.

The color #140F8F, a deep shade of Ultramarine, presents significant accessibility challenges, especially in web design. Its low luminance value of approximately 3% means that it requires very light text to achieve sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. To ensure accessibility, it's crucial to use text colors like white or very light shades of yellow or gray when using #140F8F as a background. Using darker text colors will make content difficult to read for users with visual impairments. When using this color for decorative purposes, ensure critical information is not conveyed solely through this color to accommodate users with color blindness. Consider adding alternative cues like text labels or icons for clarity. Also, avoid using it for interactive elements without clear visual affordances.
