General Information about Ultramarine

The color #1813A1, commonly known as Ultramarine, is a deep, rich shade of blue that sits distinctly in the blue color spectrum. It is characterized by its strong presence and evokes feelings of stability, trust, and sophistication. In the RGB color model, it is composed of 9.41% red, 7.45% green, and 63.14% 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, it was highly valued and often used in paintings to depict the robes of the Virgin Mary due to its rarity and expense. Today, synthetic versions are widely available, making it accessible for various applications. It is often associated with royalty, depth, and wisdom and is utilized across various industries, including design, fashion, and art.

The color #1813A1, also known as Ultramarine, presents some accessibility challenges, particularly in text-based contexts. Its dark hue demands careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background. Using #1813A1 for text on a white or light background may not meet these standards, potentially causing readability issues for users with visual impairments. To enhance accessibility, it's crucial to pair Ultramarine with very light colors such as white (#FFFFFF) or pale yellows (#FFFFE0). Careful evaluation of color combinations with accessibility testing tools is essential. Considering alternative, lighter shades of blue or adjusting background colors can significantly improve the overall user experience for individuals with diverse visual abilities. Remember that prioritizing accessibility ensures inclusivity and broadens the reach of your content.
