#1D0692

General Information about Ultramarine

Ultramarine, represented by the hex code #1D0692, is a deep blue color with a strong presence. Historically, ultramarine was derived from the precious mineral lapis lazuli, making it one of the most expensive and highly prized pigments. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was imported to Europe from mines in Asia. Today, synthetic ultramarine is readily available, retaining the color's characteristic depth and richness. In color theory, ultramarine blue is associated with royalty, wisdom, and spirituality. It is a versatile color that can evoke feelings of calmness and stability but should be used judiciously due to its darkness.

The hex color #1D0692, also known as Ultramarine, presents significant accessibility challenges, especially in web design. Its extremely dark hue results in very low contrast against lighter backgrounds, which can make text and interactive elements difficult or impossible for users with visual impairments to perceive. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. To improve accessibility, this color should ideally be paired with very light shades like white or pale yellow to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid using this color for critical elements like links or buttons unless accompanied by strong visual cues and sufficient contrast. Also avoid using this color for people with cognitive disabilities.
