General Information about Ultramarine (#1B0494)

Ultramarine, represented by the hex code #1B0494, is a deep blue color with a rich history. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' it was originally made from ground lapis lazuli, a rare and expensive gemstone imported from Afghanistan. This made ultramarine one of the most prized pigments during the Renaissance, reserved for the most important figures in paintings, such as the Virgin Mary. Today, synthetic ultramarine is readily available, but the color retains its association with luxury and sophistication. In color psychology, deep blues like ultramarine are often associated with stability, trust, and intelligence. It’s a color that conveys authority and calmness, making it popular in corporate branding and professional settings.

The hex color #1B0494, a deep ultramarine, presents several accessibility considerations for web developers. Its low luminance value means it requires careful pairing with text and other elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #1B0494 as a background, ensure that the foreground text color provides adequate contrast. Light shades of yellow, white, or light greens are often suitable choices. Tools like contrast checkers can help verify compliance. Additionally, avoid relying solely on color to convey important information, as users with color vision deficiencies may struggle to differentiate it from similar hues. Supplement color cues with text labels, icons, or patterns to ensure inclusive design. Consider the overall visual hierarchy and readability when incorporating this deep hue into your design.
