General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #090890, is a deep shade of blue with a rich history. The name 'ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from mines in Afghanistan. Historically, it was derived from the gemstone lapis lazuli and was highly prized for its vibrant and long-lasting color, often used in medieval and Renaissance paintings. Today, synthetic ultramarine is widely available, offering a more affordable alternative. This color evokes feelings of tranquility, depth, and sophistication. In color psychology, blue is often associated with stability, trust, and intelligence, making ultramarine a popular choice for branding and design where these qualities are desired. Its dark hue makes it suitable for creating a sense of depth and contrast.

The color #090890, a deep ultramarine, presents significant accessibility challenges, particularly in text applications. Its low luminance value necessitates careful consideration of color contrast ratios. When used as a foreground color, it requires a light background to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Avoid pairing it with dark grays or blacks. For interactive elements like buttons, ensure sufficient contrast for both the text and the button's background. Consider providing alternative color schemes that offer higher contrast for users with visual impairments. Using color alone to convey information should be avoided; supplement with text labels or icons. Thoroughly test color combinations with accessibility tools to ensure compliance with accessibility standards and optimal user experience for all users, including those with low vision or color blindness.
