#0D158B

General Information about Ultramarine

The color #0D158B, commonly known as Ultramarine, is a deep and intense shade of blue that evokes feelings of sophistication and depth. Its historical significance stems from its origins as a pigment derived from the rare and precious mineral lapis lazuli, making it highly valued throughout history, especially in Renaissance art. Ultramarine is characterized by its rich, non-reddish blue hue, often associated with royalty, spirituality, and intellect. In color psychology, it is believed to promote feelings of tranquility, stability, and confidence. Its high chroma and relatively low lightness make it a visually striking color that can add drama and elegance to various applications in art, design, and fashion.

The color #0D158B, a deep shade of Ultramarine, presents specific accessibility challenges in web design. Its low lightness value (approximately 8%) means it offers very little contrast against common background colors like white. According to WCAG guidelines, sufficient contrast is essential for users with visual impairments to perceive text and interactive elements effectively. When using #0D158B for text, a very light background color is crucial to meet minimum contrast ratios. Similarly, when employed for interactive elements such as buttons, ensuring a clear visual distinction through sufficient contrast helps users easily identify and understand their functions. Therefore, designers should carefully evaluate color combinations and provide alternative styling options, such as high-contrast themes, to accommodate users with diverse visual needs and comply with accessibility standards.
