#021396

General Information about Ultramarine

Ultramarine, represented by the hex code #021396, is a deep, saturated blue color that evokes feelings of stability, trust, and intelligence. Historically, ultramarine pigment was derived from the semi-precious stone lapis lazuli, making it a highly prized and expensive color, often reserved for royalty and religious figures in art. In modern color theory, ultramarine is considered a cool color, often associated with calmness and serenity. Its darkness can also convey a sense of authority and sophistication. In the digital realm, ultramarine can be used to create a sense of depth and importance, but careful consideration should be given to contrast and accessibility due to its low luminance value.

The color #021396, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its low luminance necessitates careful consideration of contrast ratios, particularly when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. Given the darkness of #021396, it's essential to pair it with very light colors, such as white or pale yellows, to ensure readability for users with visual impairments. Additionally, relying solely on color to convey information is not advisable. Incorporating supplementary cues like icons or text labels can greatly improve usability for color-blind users. Thorough testing with accessibility tools and diverse user groups is crucial to validate the accessibility of designs incorporating this color.
