About Ultramarine

Ultramarine, represented by the hex code #171187, is a deep blue color with a rich history rooted in the pigment derived from the precious mineral lapis lazuli. During the Middle Ages and Renaissance, this pigment was highly valued and costly, making Ultramarine a color reserved for royalty and significant religious figures, especially in paintings. The name 'Ultramarine' literally means 'beyond the sea,' reflecting the fact that the pigment was imported to Europe from mines in Asia. Nowadays, synthetic Ultramarine is readily available, making the color more accessible for various applications. This vibrant and intense blue evokes feelings of calmness, serenity, and sophistication. It's a color often associated with knowledge, power, integrity, and professionalism.

The accessibility of #171187 (Ultramarine) is limited, particularly for text. Its dark hue necessitates very light text colors (white or near-white) to ensure sufficient contrast for readability, meeting WCAG standards. Using darker shades of gray or other colors with low luminance contrast against Ultramarine can cause significant readability issues, especially for users with visual impairments. When used as a background, avoid pairing it with colors of similar darkness. Larger text sizes and heavier font weights can slightly improve readability, but careful color selection remains paramount. Providing sufficient contrast is crucial for ensuring that content is accessible to all users, regardless of their visual abilities. Consider using contrast checking tools to evaluate color combinations and ensure compliance with accessibility guidelines, promoting an inclusive user experience.
