General Information about Ultramarine

The hexadecimal color #1C03B1, also known as Ultramarine, is a deep, saturated shade of blue. It is composed of 11% red, 1% green, and 70% blue. In the RGB color model, this translates to R:28, G:3, B:177. Ultramarine, historically derived from the precious mineral lapis lazuli, has been prized for its rich, intense hue, particularly in fine art and decoration. Modern ultramarine is often synthetically produced, making it more accessible and affordable. Its distinctive depth and clarity make it a captivating and versatile color for both traditional and contemporary applications. The color is often associated with royalty, wisdom, and spirituality, making it a popular choice for brands and designs aiming to convey these qualities.

The color #1C03B1, a deep ultramarine, presents several accessibility considerations for web developers. Its low lightness value (approximately 6%) means it offers very poor contrast when used as text against a standard white background. This fails WCAG standards for both normal and large text sizes, making it difficult for users with visual impairments to read. To improve accessibility, consider using #1C03B1 for decorative elements or backgrounds in combination with very light text colors like white or light grey. Alternatively, use it with a darker background and very light text. Tools like contrast checkers can help ensure sufficient contrast ratios. Furthermore, avoid relying solely on this color to convey important information; supplement it with text labels or other visual cues to ensure inclusivity for all users, especially those with color vision deficiencies.
