#1A07AD

General Information about Ultramarine

The hexadecimal color #1A07AD, commonly known as Ultramarine, is a deep shade of blue with a strong presence and rich history. This color is a combination of red, green, and blue light, with relatively low red and green values and a high blue value. Ultramarine has been prized since ancient times, originally derived from the precious stone lapis lazuli, making it one of the most expensive pigments. It has been used extensively in art, particularly during the Renaissance, to depict the robes of the Virgin Mary, symbolizing holiness and royalty. Today, synthetic ultramarine is readily available, making it more accessible for a wide range of applications. Its intense hue and historical significance make it a popular choice in design and art.

The color #1A07AD, a deep ultramarine, presents several accessibility considerations. Its high darkness value means it offers excellent contrast against white text, easily meeting WCAG AA standards for normal text sizes. However, using it for text on darker backgrounds should be avoided as it can become unreadable. When paired with lighter shades of yellow or green, contrast is improved, but careful assessment is still necessary to ensure readability for users with visual impairments. In UI design, using #1A07AD as an accent color or for interactive elements can work well if clearly differentiated from the surrounding content through sufficient contrast and clear visual cues. Additionally, avoid using it as the sole indicator of functionality (e.g., a button) to accommodate users with color vision deficiencies. Proper testing with accessibility tools is crucial to ensure compliance with web accessibility guidelines.
