General Information about Ultramarine

The hex color #2203b0, also known as Ultramarine, is a deep and vibrant shade of blue. It belongs to the blue color family and is often associated with feelings of calmness, depth, and sophistication. In the RGB color model, it consists of 13.33% red, 1.18% green, and 69.02% blue. Its high blue component gives it its characteristic deep hue. Ultramarine has been historically prized as a pigment, derived from the gemstone lapis lazuli. Today, synthetic versions allow for wider availability and application. This color can evoke feelings of trust, loyalty, and authority, making it a popular choice for branding and design.

The hex color #2203b0, a deep ultramarine, presents significant accessibility challenges, primarily due to its low luminance. When used as a foreground color, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to ensure readability for users with visual impairments. Therefore, pairing #2203b0 with colors like white (#ffffff) or very light shades of gray is crucial. Avoid using it with darker colors or mid-tone shades, as this will likely result in insufficient contrast, making text or interface elements difficult to perceive. Careful consideration of color combinations is essential to provide an inclusive and accessible user experience.
