General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0A08A3, is a deep and intense shade of blue, often associated with royalty, wisdom, and spirituality. This color derives its name from the Latin 'ultramarinus', meaning 'beyond the sea', as it was originally imported from mines in Afghanistan by sea. Historically, ultramarine pigment was made from lapis lazuli, making it one of the most expensive and prized pigments used by Renaissance artists. Its unique hue results from the presence of sulfur within the mineral structure. Today, synthetic ultramarine is widely available, making the color more accessible for various applications. In color psychology, ultramarine is known to evoke feelings of tranquility, stability, and confidence, making it a popular choice for branding and design projects seeking to convey these qualities.

The color #0A08A3, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its extremely low luminance (very dark) requires careful consideration of color contrast. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, particularly for users with visual impairments. When using #0A08A3 as a background, ensure that the foreground text is a light color, ideally white or a very pale yellow, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Avoid using this color for small text or important interface elements unless the contrast is meticulously tested and adjusted. Furthermore, be mindful of users with color blindness; using color alone to convey information should be avoided. Supplement color cues with text labels or icons to ensure accessibility for all users.
