General Information About Ultramarine

The hex color #040494, also known as Ultramarine, is a deep, saturated shade of blue. In the RGB color model, it is composed of 1.57% red, 1.57% green, and 58.04% blue. This composition explains its strong blue character, with very little contribution from red and green. Ultramarine is often associated with qualities such as depth, stability, and intelligence. Its historical significance stems from the pigment derived from lapis lazuli, a semi-precious stone. This made it a highly prized and expensive color in art for centuries, often reserved for depicting important figures or religious scenes. Nowadays, synthetic ultramarine is readily available, making it a more accessible color for various applications. It remains a popular choice in design and art for its rich and captivating hue.

The hex color #040494, also known as Ultramarine, presents several accessibility considerations for web developers. Its very dark hue results in extremely low contrast against typical light backgrounds, like white. This poor contrast makes text and other visual elements difficult to read for users with visual impairments, including those with low vision or color blindness. To ensure accessibility, it's crucial to pair #040494 with a very light color for text and interactive elements. Tools like contrast checkers can help determine if the contrast ratio meets WCAG (Web Content Accessibility Guidelines) standards. Aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text to meet WCAG AA standards. For even better accessibility, aim for WCAG AAA compliance, which requires higher contrast ratios. Avoid using #040494 as the sole means of conveying information, and always provide alternative visual cues or text descriptions. Using this color sparingly and thoughtfully can contribute to a more inclusive and accessible web experience.
