About Ultramarine

The hex color #021399, commonly known as Ultramarine, is a deep and intense shade of blue. It's created by combining a very small amount of red and green with a large amount of blue in the RGB color model. In the CMYK model, it's composed almost entirely of cyan and magenta, with a touch of yellow and black. Ultramarine is often associated with feelings of serenity, depth, and sophistication. Historically, the pigment Ultramarine was derived from the precious stone lapis lazuli, making it a highly valued color in art. Today, synthetic versions allow for broader use, while retaining the color's regal and sophisticated character, and continuing to be used across different industries. Its rich hue makes it a popular choice for conveying a sense of luxury and elegance.

The color #021399, a deep ultramarine, presents significant accessibility challenges. Its extremely low luminance makes it difficult to perceive for individuals with low vision or color blindness. When used as text, it requires a very light background to meet WCAG contrast ratio guidelines. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using this color for crucial interface elements or information delivery should be avoided unless paired with careful consideration of contrast. Ensure sufficient contrast with foreground elements to avoid readability issues. Consider providing alternative high-contrast themes or customizable color options to enhance accessibility for all users. Proper testing with assistive technologies is vital to guarantee a positive user experience.
