General Information about Ultramarine

The color #090F8F, known as Ultramarine, is a deep, rich blue hue. In the RGB color model, it consists of 3.53% red, 5.88% green, and 56.08% blue. This substantial amount of blue gives the color its characteristic depth and intensity. Ultramarine has historical significance, originally derived from the precious gemstone lapis lazuli. This origin contributed to its association with royalty, luxury, and spirituality. In modern color psychology, Ultramarine is often linked to feelings of calmness, trustworthiness, and intelligence. Its association with the sea and sky further reinforces these qualities. The color is also used in several visual art designs and branding.

The hex color #090F8F, also known as Ultramarine, presents significant accessibility challenges, especially in web design. Its dark hue results in very low contrast when used with similarly dark text or interface elements. This can make content difficult or impossible for users with visual impairments to read. To ensure accessibility, it is crucial to use this color with very light foreground colors, such as white or pale yellow, to achieve a contrast ratio that meets WCAG guidelines (ideally 4.5:1 for normal text and 3:1 for large text). Tools like contrast checkers can help verify compliance. Avoid using this color for critical interactive elements unless sufficient contrast is guaranteed. Also, provide alternative styling options for users who may need them.
