General Information about Ultramarine

The hex color #040695, commonly referred to as Ultramarine, is a deep, intense shade of blue. It falls within the dark blue color spectrum and is characterized by its strong saturation and relatively low lightness. In the RGB color model, #040695 is composed of 1.57% red, 2.35% green, and 58.43% blue. This composition explains the color's pronounced blue hue. Ultramarine, historically, was derived from the mineral lapis lazuli, making it a highly prized pigment used in paintings and other forms of art. Today, synthetic versions allow for broader application across various industries, including textiles, plastics, and coatings. Its dark and captivating nature makes it suitable for creating a sense of depth, luxury, or mystery in visual designs.

The hex color #040695, also known as Ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its extremely dark hue results in very low contrast against light backgrounds, making text or graphical elements difficult to discern. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. To ensure accessibility, web developers should avoid using #040695 for text or important interface elements on light backgrounds. If it is necessary, consider using a very light color such as #ffffff or #f0f0f0 as a foreground to achieve acceptable contrast ratios. Tools like contrast checkers can help measure and verify compliance with accessibility standards. In situations where Ultramarine is part of a brand identity, explore alternative color combinations that maintain brand recognition while prioritizing accessibility for all users.
