About Ultramarine

Ultramarine, represented by the hex code #130B90, is a deep and intense shade of blue. Historically, the pigment ultramarine was derived from the gemstone lapis lazuli, making it highly prized and expensive, often reserved for the most important commissions. Today, synthetic ultramarine is readily available, offering the same vibrant hue at a fraction of the cost. This color is often associated with royalty, the sea, and a sense of depth and mystery. In color psychology, deep blues like ultramarine can evoke feelings of calmness and stability, while also suggesting power and authority. It is a color that commands attention and adds a touch of elegance to designs.

The color #130B90, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white background, the contrast ratio is substantially low, making it difficult for users with visual impairments to read. To ensure accessibility, it's crucial to pair this dark blue shade with much lighter colors, such as whites, creams, or very light yellows, to meet WCAG (Web Content Accessibility Guidelines) standards for contrast. Using online contrast checker tools can help verify that the color combinations meet accessibility requirements. Additionally, consider providing alternative visual cues, such as underlines or icons, to convey information for users who may struggle to differentiate colors. Avoid using this color for critical information without sufficient contrast.
