Ultramarine

#050E93

General Information

The hex color #050E93, also known as Ultramarine, is a deep and rich shade of blue. In the RGB color model, it is composed of 2.0% red, 5.5% green, and 57.6% blue. This composition gives it a strong blue dominance, resulting in its distinctive appearance. Ultramarine has a long and storied history, originally derived from the rare and expensive mineral lapis lazuli. During the Middle Ages and Renaissance, it was highly prized by artists and was often reserved for depicting important figures, such as the Virgin Mary. The name "ultramarine" literally means "beyond the sea," reflecting its origin from pigments imported from distant lands. Today, synthetic ultramarine pigments are widely available, making this beautiful color more accessible for various applications. Its deep, saturated hue evokes feelings of calmness, stability, and sophistication.

The color #050E93, a deep ultramarine, presents significant accessibility challenges, especially when used for text or interactive elements. Its very low luminance (darkness) means that it requires extremely light foreground colors to achieve sufficient contrast ratios as defined by WCAG (Web Content Accessibility Guidelines). A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG AA standards. When pairing #050E93 with white or very light shades of yellow or green, careful testing is essential to ensure readability for users with visual impairments. Furthermore, consider providing alternative color schemes that offer better contrast for users who may need them. Avoid using this color as the sole indicator for important interactive elements such as links or buttons, as users with color blindness may not be able to distinguish them. Always provide additional visual cues, such as underlines or icons, to enhance usability for all users. Proper implementation of ARIA attributes can also significantly improve accessibility for assistive technologies.
