Ultramarine

#1F0EA5

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1F0EA5, is a deep blue pigment derived from the mineral lapis lazuli. Historically, it was highly valued and often more expensive than gold, making it a color reserved for royalty and religious figures in art. Its intense, rich hue is due to the presence of sulfur-containing compounds within the mineral's crystal structure. Today, synthetic ultramarine is widely available, offering the same vibrant color at a fraction of the cost. In color theory, ultramarine is considered a cool color, associated with feelings of tranquility, stability, and wisdom. It is widely used in various applications, including art, design, and manufacturing, due to its captivating appearance and symbolic connotations. Its spectral reflectance is low in the red and green regions, resulting in the perception of deep blue.

The color #1F0EA5, a deep ultramarine, presents some accessibility challenges. Its low luminance value of approximately 3% means it requires careful consideration when used as a foreground color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. Given its darkness, #1F0EA5 necessitates a very light background to meet these standards. Using it with text sizes smaller than 18pt (or 14pt bold) is strongly discouraged unless paired with an adequately contrasting color. Additionally, avoid using it to convey crucial information without redundant cues, as those with visual impairments may struggle to differentiate it from similar dark shades. Consider providing alternative visual cues, such as icons or text labels, to ensure inclusivity.
