General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #010B97, is a deep, saturated blue hue often associated with royalty, wisdom, and sophistication. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' the name reflects its historical origins as a pigment sourced from lapis lazuli, a semi-precious stone imported from distant lands. In the RGB color model, Ultramarine consists of 0.4% red, 4.3% green, and 59.2% blue. Its high blue component contributes to its intense and captivating appearance. Ultramarine's symbolic associations make it a popular choice in branding, design, and art, conveying messages of trust, stability, and intellect. Understanding the color's properties and historical context can enhance its effective use in various creative applications.

The color #010B97, also known as Ultramarine, presents significant accessibility challenges, especially when used as a primary color for text or interactive elements. Its very low luminance creates poor contrast against light backgrounds, making it difficult for users with visual impairments, including those with low vision or color blindness, to discern content effectively. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine falls far short of these recommendations when paired with common background colors like white or light gray. To improve accessibility, it is crucial to use Ultramarine sparingly for text and only in conjunction with very light, high-contrast backgrounds, or to use it for purely decorative purposes. Consider using Ultramarine for larger graphic elements where legibility is not paramount and ensure sufficient spacing and clear visual cues around interactive elements to aid navigation for all users.
