General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0F138B, is a deep and intense blue color with a rich history and diverse applications. The term 'ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally derived from the precious gemstone lapis lazuli, imported from distant lands, primarily Afghanistan. This made it one of the most expensive and highly prized pigments during the Middle Ages and Renaissance, often reserved for depicting the robes of the Virgin Mary in religious paintings. Today, synthetic ultramarine is widely available, making it more accessible for various applications. Its unique hue is characterized by its slight reddish undertones compared to other blue pigments, contributing to its distinct and captivating appearance. Ultramarine continues to be valued for its depth, brilliance, and historical significance.

The color #0F138B, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its dark hue results in very low contrast against typical light backgrounds, such as white or light gray. This low contrast makes it difficult for users with visual impairments, including those with low vision or color blindness, to read text or distinguish elements using this color. To ensure accessibility, it is crucial to pair #0F138B with significantly lighter colors that meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Furthermore, avoid using #0F138B as the sole means of conveying information, as color blindness can prevent some users from perceiving the intended message. Providing alternative visual cues, such as text labels or icons, is essential for inclusive design. Careful consideration of color combinations and adherence to accessibility standards are necessary to make content accessible to all users.
