About Ultramarine (#100F89)

Ultramarine, represented by the hexadecimal color code #100F89, is a deep, saturated shade of blue. Historically, ultramarine pigment was derived from the rare and costly mineral lapis lazuli, making it a prized color among artists. The name "ultramarine" literally means "beyond the sea," as the pigment had to be imported to Europe from mines in Asia. Nowadays, synthetic ultramarine is widely available, offering the same vibrant hue at a more accessible price. In color psychology, ultramarine is often associated with feelings of serenity, depth, and wisdom, making it a popular choice for branding, design, and artistic applications.

The color #100F89, a deep shade of blue also known as Ultramarine, presents some accessibility challenges. Its dark hue results in a low contrast ratio against lighter backgrounds, which can make text and interactive elements difficult to read for users with visual impairments. When using this color for text, it is essential to pair it with a very light background color, such as white or a pale yellow, to ensure sufficient contrast. Following WCAG guidelines for contrast ratios is crucial. Additionally, avoid using #100F89 as the sole indicator of important information; supplement it with text labels, icons, or other visual cues to provide redundancy and improve accessibility for all users.
