About Ultramarine

The color #001198, commonly known as Ultramarine, is a deep and intense shade of blue. It derives its name from the pigment originally made from lapis lazuli, a semi-precious stone mined in Afghanistan and used by artists since the Middle Ages. Because of its origin and the difficulty in obtaining it, ultramarine was a highly prized and expensive pigment, often reserved for depicting the robes of the Virgin Mary in religious paintings. Today, synthetic ultramarine is readily available, making it a more accessible and affordable color. In color theory, ultramarine is considered a cool color, often associated with feelings of calmness, serenity, and stability. It is widely used in various applications, from art and design to branding and fashion, for its rich and captivating appearance. It's a color often associated with trustworthiness.

The hex color #001198, a deep shade of ultramarine, presents several accessibility considerations for web developers. Due to its low luminance, it's crucial to ensure sufficient contrast when used as text or background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a light color like white or a very pale yellow for text on a #001198 background would likely meet these requirements. Developers should avoid pairing #001198 with other dark colors, as this would make content difficult to read for users with visual impairments. Tools like contrast checkers can assist in verifying compliance. Furthermore, avoid relying solely on color to convey important information; supplement with text labels or other visual cues.
