General Information about Ultramarine

The color #0F1189, commonly known as Ultramarine, is a deep and intense shade of blue. It falls within the blue color family, characterized by its strong presence and association with qualities such as depth, stability, and trust. Historically, Ultramarine was derived from the precious gemstone Lapis Lazuli, making it a highly prized pigment for artists throughout the ages. Today, it is synthetically produced, retaining its vibrant and captivating hue. In color psychology, Ultramarine is often linked to intelligence, confidence, and authority. Its commanding nature makes it a popular choice in corporate branding, where it is used to convey professionalism and reliability. In digital design, Ultramarine can add a touch of sophistication, but care must be taken to ensure adequate contrast and readability against backgrounds.

The color #0F1189, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its extremely dark hue results in very low contrast against typical light backgrounds like white or light gray. This can make text or other visual elements using this color difficult to read for users with visual impairments, including those with low vision or color blindness. To ensure accessibility, it is crucial to use a sufficiently light color for text or interactive elements placed on an Ultramarine background. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, and 3:1 for large text, to meet WCAG (Web Content Accessibility Guidelines) standards. Tools like contrast checkers can help verify compliance. It's often best to pair Ultramarine with very light yellows, whites, or even pale blues to achieve adequate contrast and readability. Consider also using larger font sizes or bold text to improve legibility against this dark color.
