General Information about Ultramarine

Ultramarine (#050394) is a dark shade of blue, historically derived from the precious mineral lapis lazuli. This color is known for its deep, intense hue, often associated with royalty and religious iconography. In the RGB color model, #050394 is composed of 2% red, 1% green, and 58% blue. Its corresponding values in other color spaces are approximately: CMYK (91, 99, 0, 42), HSL (241, 98%, 29%), and HSV (241, 99%, 58%). Ultramarine's hexadecimal representation makes it easily usable in web design and digital art, though care should be taken to ensure adequate contrast with surrounding elements due to its darkness.

The color #050394, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its very low luminance (a measure of perceived brightness) results in poor contrast against lighter backgrounds, making text and interface elements difficult to read. According to WCAG guidelines, sufficient contrast ratios are crucial for readability. To ensure accessibility, it's essential to pair this color with very light foreground colors, such as white or very pale yellows. Tools are available to check contrast ratios and adherence to WCAG standards. Avoid using this color for critical interface elements or large blocks of text unless paired with an appropriately contrasting color. Consider alternative, lighter shades of blue or purple if accessibility is a primary concern. Also, avoid using this color as the only way to communicate information, include text or other visual cues.
