#1D0C8C

General Information about Ultramarine

Ultramarine, represented by the hex code #1D0C8C, is a deep, vivid blue color historically derived from the precious gemstone lapis lazuli. The name 'ultramarine' literally means 'beyond the sea,' reflecting its origin as a pigment imported from distant lands. In color theory, ultramarine is considered a cool color, often associated with depth, stability, and tranquility. It is a popular choice in various fields, including art, design, and fashion, where it can evoke feelings of sophistication and elegance. The color's richness and intensity make it a versatile option for creating both bold statements and subtle accents. Due to its historical significance and aesthetic appeal, ultramarine continues to be a widely admired and utilized color.

The color #1D0C8C, a deep ultramarine, presents significant accessibility challenges, particularly in web design. Its dark hue results in very low contrast against standard white backgrounds, failing WCAG (Web Content Accessibility Guidelines) standards for text and non-text contrast. This can cause readability issues for users with visual impairments, including those with low vision or color blindness. To improve accessibility, it is strongly recommended to pair this color with much lighter shades, such as yellows, light blues, or even off-whites. When using #1D0C8C for text, ensure that the background color provides a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Consider providing alternative color schemes that offer higher contrast options to accommodate diverse user needs and preferences. Avoid using this color for essential UI elements without careful consideration of its impact on accessibility.
