General Information about Ultramarine (#10168B)

#10168B, also known as Ultramarine, is a deep, rich shade of blue within the blue color family. It evokes feelings of serenity, stability, and authority. Historically, ultramarine pigment was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly valued pigments during the medieval and Renaissance periods. Due to its cost, it was often reserved for painting the robes of the Virgin Mary and other important figures. In modern color theory, #10168B is positioned towards the cooler end of the spectrum. It is created by combining small amounts of green and red with a larger amount of blue. Its hex code, #10168B, indicates the specific balance of these components.

The color #10168B, a deep shade of ultramarine, presents accessibility considerations, particularly in web design. When used as text, it requires careful attention to contrast ratios against background colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Using #10168B for text on a white background might not meet these standards, potentially causing readability issues for users with visual impairments. It's essential to test color combinations using accessibility tools to ensure compliance. When used for interactive elements like buttons or links, sufficient color contrast is even more critical to ensure that users can easily identify and interact with them. Furthermore, avoid using color as the sole means of conveying information; always provide alternative cues such as text labels or icons.
