General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1C05A5, is a deep, vivid shade of blue. Its name originates from the Latin "ultramarinus," meaning "beyond the sea," reflecting its historical source: the precious mineral lapis lazuli, imported from distant lands. This pigment was highly valued for centuries, often reserved for royalty and religious art, especially in depictions of the Virgin Mary's robes. In modern color theory, Ultramarine is recognized for its ability to evoke feelings of calmness, serenity, and sophistication. It is often associated with qualities such as trust, loyalty, and intelligence. In digital applications, #1C05A5 can be used to create a sense of depth and visual interest. However, care should be taken to ensure sufficient contrast with text and other elements for accessibility.

The color #1C05A5, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a low luminance value, which means it requires careful attention to contrast ratios. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. When using #1C05A5 as a background, ensure that the foreground text color provides a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. White or light shades of yellow or green are often suitable choices. It's also important to avoid using #1C05A5 for essential visual elements like links or buttons without additional cues, such as underlines or borders, to ensure they are easily identifiable by all users. Regularly test color combinations with accessibility tools to ensure compliance and inclusivity.
