Ultramarine

#13009B

General Information about Ultramarine

Ultramarine, represented by the hex code #13009B, is a deep blue pigment originally derived from the precious stone lapis lazuli. Its name literally means 'beyond the sea,' reflecting its origins as an imported pigment. Historically, ultramarine was highly prized and more expensive than gold, making it a color reserved for the most important commissions, such as the robes of the Virgin Mary in Renaissance paintings. Today, synthetic ultramarine is widely available, making it an accessible color for a range of applications. It is known for its rich, intense blue hue and is valued for its stability and lightfastness. Ultramarine is a popular choice in art, design, and fashion, offering a sense of depth and sophistication.

The color #13009B, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its very low lightness value (close to black) means that text rendered in this color requires extremely light foreground colors to meet WCAG (Web Content Accessibility Guidelines) contrast ratios. For example, using white text on a #13009B background is essential for readability. It is crucial to avoid pairing this color with mid-tone grays or darker shades, as this will likely fail accessibility checks, making content unreadable for users with visual impairments. Careful consideration of color contrast is paramount when implementing this color to ensure an inclusive user experience. The use of tools that measure contrast ratios can be invaluable during the design process. Also, providing alternative color schemes for users who need higher contrast or have color vision deficiencies is a good practice.
