General Information about Ultramarine

The hex color #0C108F, commonly known as Ultramarine, is a deep and intense shade of blue. It is located in the blue region of the color spectrum, possessing a strong saturation and relatively low brightness. Historically, Ultramarine was derived from the mineral lapis lazuli, making it a highly prized and expensive pigment. In modern color theory, Ultramarine is often associated with qualities such as depth, stability, and wisdom. It's a popular choice in design and art when a sense of formality or authority is desired. However, its dark nature means it should be carefully considered for accessibility in visual mediums, particularly concerning contrast ratios with text or other visual elements.

The hex color #0C108F, also known as Ultramarine, presents significant accessibility challenges, especially in web design. Its dark hue results in a low contrast ratio against light backgrounds, making text and other elements difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine often fails to meet these standards, necessitating careful consideration of foreground colors. To improve accessibility, it's advisable to pair #0C108F with very light colors such as white or light yellow, and to increase the font size and weight to enhance readability. Utilizing contrast checkers can help ensure compliance with accessibility standards and provide a better user experience for everyone.
