#1705AF

General Information About Ultramarine

The color #1705AF, known as Ultramarine, is a deep, vibrant shade of blue that sits between blue and violet on the color spectrum. It is characterized by its high saturation and strong, almost electric hue. The name "Ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the original pigment was derived from the semi-precious stone lapis lazuli, which was imported to Europe from distant lands via sea routes. In the RGB color model, #1705AF is composed of 9.02% red, 1.96% green, and 68.63% blue. In the CMYK color model, it consists of 87% cyan, 97% magenta, 0% yellow, and 31% black. Ultramarine is often associated with qualities such as trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. Its rich and intense color makes it suitable for conveying authority, stability, and sophistication.

The color #1705AF, Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low lightness value (approximately 5%) results in very poor contrast against standard white backgrounds. This lack of contrast makes text and other visual elements difficult to discern, potentially causing eye strain and hindering readability. According to WCAG guidelines, this color would fail most contrast ratio tests for both normal and large text sizes. To improve accessibility, it is crucial to pair Ultramarine with much lighter colors that provide a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Alternatives include using Ultramarine sparingly, such as for decorative accents, or employing it with careful consideration of font size and weight. Implementing a color contrast checker during the design process is highly recommended to ensure compliance with accessibility standards and create a more inclusive user experience. A white or very light yellow color is recommended for text on this background. Ensuring sufficient contrast is paramount for users with low vision or color blindness, as well as those using devices in high-glare environments.
