General Information about Ultramarine (#030197)

The color #030197, commonly known as Ultramarine, is a dark shade of blue with a strong presence. It is a color that evokes feelings of depth, intelligence, and authority. In the RGB color model, it is composed of 1.18% red, 0.39% green, and 59.22% blue. This combination results in a color that is heavily weighted towards the blue end of the spectrum, giving it its characteristic deep blue appearance. Ultramarine has a rich history, originally derived from the precious gemstone lapis lazuli. The color's association with rarity and value has contributed to its continued appeal in art, design, and fashion. Modern production methods have made the pigment more accessible, but its connection to luxury remains.

The hex color #030197, a deep ultramarine, presents considerable accessibility challenges. Its extremely low lightness value makes it unsuitable for body text, as the contrast against a standard white background would be far below the WCAG guidelines. At a minimum contrast ratio of 4.5:1 is required for normal text and 3:1 for large text. This color fails to meet even the large text requirement. To improve accessibility, it should primarily be used for decorative elements or backgrounds when paired with very light text. When used as a link color, sufficient contrast must be provided in its hover, focus, and active states, which can be achieved by adjusting the color's lightness or hue. Careful consideration should be given to users with visual impairments; providing alternative visual cues or text equivalents alongside this color will significantly improve their experience. Avoid using this color as a primary element for conveying information without sufficient supporting visual elements with high contrast.
