General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #17098F, is a deep and intense shade of blue. Historically, Ultramarine was derived from the precious gemstone lapis lazuli, making it a highly valued pigment, especially in Renaissance painting. The name 'Ultramarine' literally means 'beyond the sea,' reflecting its origin from stones imported into Europe from Asia. Today, synthetic versions of Ultramarine are readily available, but the color still retains its association with richness and sophistication. In color psychology, Ultramarine blue often symbolizes trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. It's a color that can evoke feelings of calmness and serenity, as well as power and authority. The RGB values for Ultramarine are R:23, G:9, B:143.

The color #17098F, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its dark hue results in very low contrast against typical light backgrounds (such as white). This low contrast makes it difficult for users with visual impairments, including those with low vision or color blindness, to read text or distinguish elements using this color. To ensure accessibility, it's crucial to pair Ultramarine with very light colors, like white (#FFFFFF) or a pale yellow, to achieve a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards, ideally a ratio of 4.5:1 for normal text and 3:1 for large text. Using it for decorative elements or backgrounds is acceptable if it doesn't interfere with readability. Consider using accessibility evaluation tools to verify contrast ratios and simulate how the color appears to users with different types of color blindness. Avoid using it for crucial information that needs to be universally accessible.
