General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1A0088, is a deep, vivid blue color with a slight violet undertone. Its name derives from the Latin 'ultramarinus', meaning 'beyond the sea', as it was originally made from lapis lazuli imported from Asia. Historically, ultramarine pigment was highly prized, often more expensive than gold, and reserved for the most important artistic commissions, such as the robes of the Virgin Mary in Renaissance paintings. Modern synthetic ultramarine is more affordable and widely available, retaining the same beautiful hue. In color theory, ultramarine is considered a cool color, evoking feelings of calmness, serenity, and stability. It lies between blue and violet on the color spectrum and can be used to create a sense of depth and sophistication in various applications.

The color #1A0088, a deep ultramarine, presents several accessibility considerations for web development. Its dark nature implies sufficient contrast is crucial when paired with text or other interactive elements. According to WCAG guidelines, contrast ratios should meet specific thresholds (4.5:1 for normal text, 3:1 for large text) to ensure readability for users with visual impairments. Lighter colors like white, light gray, or pastel shades would generally work best as foreground colors against #1A0088. Furthermore, avoid using this color as the sole means of conveying information; always provide alternative cues like text labels or icons. When implementing this color, test it with accessibility evaluation tools to confirm compliance with accessibility standards and consider the needs of users with different types of color vision deficiencies.
