General Information about Ultramarine

The color #040395, also known as Ultramarine, is a deep and intense shade of blue that evokes feelings of calmness, trust, and sophistication. It belongs to the blue color family and is characterized by its high saturation and relatively low brightness. In the RGB color model, it consists of 4 red, 3 green, and 149 blue. Its usage is more common in digital applications rather than print, where color accuracy can be guaranteed. Ultramarine blue has a rich history, originally derived from the precious gemstone lapis lazuli, making it a highly valued pigment in art for centuries. Its synthetic equivalent is now widely available, offering a cost-effective alternative while maintaining a similar aesthetic appeal. Due to its historical association with royalty and spirituality, it can be used to create designs that convey a sense of authority and reverence.

The hex color #040395, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its extremely low luminance (very close to black) means that text or other elements using this color as a background will require very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #040395 as a background necessitates a foreground color like white or a very light shade of yellow to meet these standards. Failure to adhere to these contrast ratios can lead to readability issues, particularly for users with visual impairments. When using this color, careful consideration must be given to color pairings and text sizes to provide an inclusive and accessible experience for all users. Testing with accessibility tools is highly recommended.
