Ultramarine is often associated with feelings of depth, stability, and intelligence. Historically, ultramarine pigment was derived from the semi-precious stone lapis lazuli, making it one of the most expensive and highly prized pigments. Today, it is synthetically produced, making it more accessible for various applications. The color's unique blend of blue and purple hues makes it versatile for design, art, and fashion.

The color #140C8F, a deep ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a low luminance value, which means it requires careful pairing with text and background colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet Level AA compliance. For Level AAA, these ratios increase to 7:1 and 4.5:1 respectively. Therefore, when using #140C8F as a background color, it is crucial to use very light text colors, such as white or light yellow, to achieve adequate contrast. Additionally, avoid using this color for essential UI elements or interactive components without providing clear visual cues, such as borders or icons, to ensure users can easily identify and interact with them. Providing alternative high-contrast themes will improve the experience for users with visual impairments. Color blindness simulators can help designers check how the color is perceived by users with different types of color vision deficiencies.
