#150692

General Information about Ultramarine

Ultramarine, represented by the hex code #150692, is a deep and saturated blue color. It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the original pigment was made from lapis lazuli imported from faraway lands. Historically, ultramarine was highly valued and expensive, often reserved for depicting the robes of the Virgin Mary in religious paintings. Today, synthetic ultramarine is readily available, making it a widely used color in various applications. In color theory, ultramarine is considered a cool color, associated with feelings of calmness, stability, and depth. It is often used to evoke a sense of trust and professionalism. The color #150692 has a relatively low luminance, making it appear darker. This specific shade leans towards the indigo spectrum, exhibiting a strong blue hue with subtle violet undertones, contributing to its rich and intense appearance.

The color #150692, a deep ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value of approximately 3% means that text rendered in this color requires very light foreground colors to meet WCAG (Web Content Accessibility Guidelines) contrast ratios. For standard text (AA level), a contrast ratio of 4.5:1 is needed, while large text requires a 3:1 ratio. Using white (#FFFFFF) as the foreground color provides a contrast ratio of about 15:1, which meets the AAA level. However, lighter shades of gray or colors closer to #150692 will likely fail accessibility checks. Designers should carefully choose foreground colors and provide options for users to adjust color schemes if necessary, ensuring readability and usability for all individuals, including those with low vision or color blindness. Consider alternative color combinations or provide a high-contrast mode to enhance accessibility.
