General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1A0A91, is a deep, vivid shade of blue. It's a color traditionally associated with royalty, wisdom, and spirituality. In the RGB color model, Ultramarine consists of 10.2% red, 3.92% green, and 56.86% blue. This color finds its roots in the pigment derived from the precious stone lapis lazuli, hence its historical value and association with high status. Ultramarine has been used extensively in art, particularly during the Renaissance, where it was prized for its intense and lasting color. Modern applications range from digital design and branding to fashion and interior decoration. The color evokes feelings of calmness, depth, and authority, making it suitable for various creative and professional contexts. However, due to its darkness, it's crucial to consider contrast ratios when using it in web design to ensure accessibility.

The hex color #1A0A91, also known as Ultramarine, presents significant accessibility challenges, particularly for text and interactive elements. Its very dark hue results in low contrast against lighter backgrounds, making it difficult for users with visual impairments to discern content. According to WCAG guidelines, sufficient contrast ratios are crucial for readability. To ensure accessibility, pair Ultramarine with very light colors, such as white or pale yellow, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using color alone to convey information is not recommended; supplement it with text labels or other visual cues. Consider using online contrast checker tools to verify compliance with accessibility standards before deploying this color in web designs. Thoroughly testing with users who have different visual abilities is also essential to validate its usability.
