General Information About Ultramarine

Ultramarine, represented by the hexadecimal color code #10108B, is a deep, intense shade of blue. It derives its name from the pigment originally made from lapis lazuli, a semi-precious stone. Historically, Ultramarine was highly prized and expensive, making it a color reserved for significant artistic works and religious iconography. Today, synthetic Ultramarine is widely available, making it accessible for various applications. In color theory, Ultramarine evokes feelings of calmness, serenity, and sophistication. It is often associated with the sea, sky, and vastness, and is used to represent depth, wisdom, and stability. Its rich hue makes it a popular choice for designs aiming to convey a sense of luxury or trustworthiness. The color is composed of relatively low amounts of red and green, and a high amount of blue in the RGB color model.

The color #10108B, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text to ensure readability, adhering to WCAG guidelines. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Considering individuals with visual impairments, including those with low vision or color blindness, is crucial. Avoid using #10108B as a primary color for essential information without sufficient contrast. Using tools to check color contrast ratios is highly advisable during the design process. Also, avoid using this color to convey information without additional visual cues, like text labels or icons, since users with color vision deficiencies may not be able to distinguish it from other similar colors. Generally, use lighter shades or tints of other colors instead of pure #10108B to increase accessibility.
