General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #170695, is a deep, rich shade of blue. Historically, Ultramarine was derived from the precious gemstone lapis lazuli, making it a highly valued pigment, especially during the Renaissance. The name 'Ultramarine' literally means 'beyond the sea,' referring to the pigment's origin from overseas. Chemically, it is a complex sodium aluminosilicate with sulfur. In modern times, synthetic Ultramarine is widely available, offering the same vibrant color at a more affordable cost. This color is often associated with royalty, intelligence, and depth. It evokes feelings of calmness, authority, and sophistication, making it a popular choice in various applications.

The color #170695, also known as Ultramarine, presents significant accessibility challenges due to its dark hue. When used as a background color, it requires very light text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Ultramarine, being a deep shade of blue, often falls short of these ratios with darker text options. Therefore, it is crucial to pair it with colors like white or very light shades of yellow or gray to meet accessibility standards. Additionally, avoid using this color for elements that convey important information through color alone, as users with color vision deficiencies may not be able to distinguish them effectively. Providing alternative cues, such as text labels or icons, is highly recommended to enhance accessibility.
