About Ultramarine (#0A0091)

The color #0A0091, commonly known as Ultramarine, is a deep and rich shade of blue. It belongs to the blue color family, specifically a dark variant that evokes feelings of depth, stability, and sophistication. In the RGB color model, it consists of 3.92% red, 0% green, and 56.86% blue. The name "Ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from mines in Afghanistan by sea. Historically, ultramarine was highly valued and expensive, often used in paintings to depict important figures and religious scenes. Today, synthetic versions are readily available, making it accessible for various applications, including digital design, printing, and manufacturing. Its unique spectral properties give it a distinct appearance, setting it apart from lighter blues.

The color #0A0091, a deep ultramarine, presents some accessibility challenges, particularly in text applications. Due to its low luminance, it is crucial to ensure sufficient contrast against background colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text (14pt bold or 18pt regular). Using #0A0091 for text on a white or very light background may not meet these guidelines, potentially causing readability issues for users with visual impairments. To improve accessibility, consider using lighter shades of blues or pairing it with contrasting colors like yellows or whites. Tools like contrast checkers can help evaluate the compliance of your color choices with accessibility standards, ensuring that your content is usable by a wider audience. Proper color selection is paramount to creating inclusive and user-friendly designs.
