General Information about Ultramarine (#210197)

The hex color #210197, also known as Ultramarine, is a deep, saturated blue hue residing in the blue-violet spectrum. It is a dark color with a relatively low brightness. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it an expensive and highly valued pigment, particularly during the Renaissance. Its name literally means 'beyond the sea,' reflecting its origin from overseas sources. Today, synthetic ultramarine is widely available, making it accessible for various applications. This color is often associated with depth, stability, and sophistication. It can evoke feelings of calmness, trust, and authority, making it a popular choice in branding and design.

The hex color #210197, a deep shade of ultramarine, presents significant accessibility challenges, especially in web design. Its low luminance value necessitates careful consideration of color contrast. When used as a background, it requires very light text (white or near-white) to ensure readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Conversely, using it for text requires a very light background. Avoid pairing this color with mid-tone shades, as they will likely fail accessibility checks. Designers must also consider users with visual impairments who may perceive colors differently. Providing alternative color schemes or allowing users to customize the color palette is highly recommended to improve accessibility and user experience. Careful attention to these details will help make content accessible to a wider audience.
