General Information about Ultramarine

The hex color #171388, also known as Ultramarine, is a deep and intense shade of blue with a strong presence. In the RGB color model, it consists of 9.02% red, 7.45% green, and 53.33% blue. This combination gives it a rich and slightly mysterious quality. Ultramarine historically refers to a pigment derived from the semi-precious stone lapis lazuli, making it a highly valued and expensive color. Today, synthetic versions provide a more accessible alternative. In color psychology, deep blues are often associated with trustworthiness, intelligence, and stability. This makes #171388 a popular choice for branding and design elements where conveying these qualities is important. Its depth also lends itself well to creating a sense of sophistication and elegance.

The hex color #171388, also known as Ultramarine, presents specific accessibility challenges, especially when used for text or interactive elements. Due to its dark hue, it requires careful consideration of color contrast to ensure readability and usability. According to WCAG guidelines, sufficient contrast between foreground and background colors is crucial for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #171388 as a background, it's essential to pair it with a light text color, such as white (#FFFFFF) or a very pale yellow, to meet these contrast requirements. Tools like WebAIM's contrast checker can assist in verifying compliance. Failing to provide adequate contrast can exclude users with low vision or color blindness, diminishing the overall accessibility of the website or application. Using this color for decorative elements is acceptable, but ensure no crucial information relies solely on its visibility against a similar-toned background.
