General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0F0E8A, is a deep, saturated blue hue historically derived from the precious mineral lapis lazuli. The name "ultramarine" literally means "beyond the sea," reflecting its origins as a pigment imported into Europe from Asia. In color theory, ultramarine sits between blue and violet on the color wheel. Its RGB values are R: 15, G: 14, B: 138. Due to its dark nature, it is less reflective and can absorb most of the visible light spectrum. This color is often associated with royalty, wisdom, and stability, and it’s a popular choice for branding and design where a sense of trustworthiness and sophistication is desired.

The color #0F0E8A, a deep ultramarine, presents several accessibility considerations for web design. Its low luminance value of approximately 1% means it offers very little contrast against a standard white background. This severely impacts readability for users with visual impairments. To ensure accessibility, a very light color such as white or a pale yellow should be used as the foreground text color. Using online contrast checkers is highly recommended to confirm the contrast ratio meets WCAG guidelines (ideally a minimum of 4.5:1 for normal text and 3:1 for large text). Avoid using this color for essential interactive elements without careful attention to contrast. Furthermore, when used in charts or data visualizations, ensure sufficient color differentiation with other data points to avoid confusion. Providing text labels is also crucial.
