General Information about Ultramarine

Ultramarine, represented by the hex code #0E138A, is a deep, vivid blue color with a rich history. The term 'ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from mines in Afghanistan. It was highly prized in the Middle Ages and Renaissance, often more expensive than gold, and was predominantly used by artists for depicting the robes of the Virgin Mary. Chemically, the natural pigment is a complex sodium aluminosilicate with sulfur. Modern ultramarine is often synthesized, making it more affordable and readily available. In color theory, ultramarine is considered a cool color, often associated with tranquility, depth, and sophistication. Its high chroma makes it stand out and capture attention, making it suitable for various applications in art, design, and branding. The RGB value is R:14, G:19, B:138.

The hex color #0E138A, also known as Ultramarine, presents specific accessibility challenges, especially in web design. Its dark hue results in low contrast when paired with similarly dark text or backgrounds, potentially hindering readability for users with visual impairments. To ensure inclusivity, it's crucial to use this color with light-colored text or backgrounds, adhering to WCAG guidelines for contrast ratios. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Tools like contrast checkers can help evaluate compliance. Additionally, avoid relying solely on color to convey information, as colorblind users may struggle to differentiate it from other dark shades. Providing alternative cues, such as text labels or icons, enhances accessibility. Thoughtful consideration of these factors is essential for creating user-friendly and accessible designs.
