About Ultramarine (#2104af)

Ultramarine, represented by the hex code #2104af, is a deep blue color with a rich history. Originally derived from the precious mineral lapis lazuli, Ultramarine was highly valued as a pigment in medieval and Renaissance art. Its name literally means 'beyond the sea,' reflecting its origins from minerals imported into Europe from Asia. Today, synthetic versions of Ultramarine are widely available, making it a more accessible and affordable color. In color theory, Ultramarine is considered a cool color, evoking feelings of calmness, serenity, and wisdom. It is often associated with royalty, intelligence, and stability. Its deep hue makes it suitable for creating a sense of depth and mystery in designs.

The hex color #2104af, also known as Ultramarine, presents significant accessibility challenges. Its dark hue results in low contrast against lighter backgrounds, potentially making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability and usability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ultramarine often falls short of these recommendations when paired with common background colors like white or light gray. To improve accessibility, consider using Ultramarine sparingly and pairing it with high-contrast text colors like white or light yellow. Alternatively, explore lighter shades of blue or completely different color palettes that inherently offer better contrast.
