About Ultramarine (#031395)

The color #031395, commonly known as Ultramarine, is a deep and intense shade of blue. This color is part of the blue color family and is often associated with depth, stability, and intelligence. In the RGB color model, it consists of 1.18% red, 7.45% green, and 58.82% blue. The name "Ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," because the pigment was originally imported from Asia. Historically, it was made from ground lapis lazuli, making it a highly valued pigment. Today, synthetic versions offer the same hue at a more accessible cost. This particular shade of blue is often used to evoke a sense of calmness and trust, making it a popular choice for branding and design.

The hex color #031395, a deep ultramarine, presents significant accessibility challenges. Its low luminance value of 0.005 means it offers very poor contrast against a standard white background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. This color fails to meet these requirements, making text illegible for users with low vision or color blindness. When used as a background color, it should be paired with extremely light text (almost white) to improve readability. Avoid using it for essential interactive elements or informational text without careful consideration of the contrast. Tools like contrast checkers can help ensure compliance with accessibility standards, preventing exclusion of users who require sufficient contrast to perceive content effectively. To improve accessibility, consider using a lighter shade of blue or combining it with a high contrast color like white or yellow.
