Ultramarine

#040197

General Information About Ultramarine

Ultramarine, represented by the hex code #040197, is a deep blue pigment originally derived from the precious mineral lapis lazuli. Its name, literally meaning "beyond the sea", reflects its historical journey from mines in Asia to Europe. This pigment was highly prized by Renaissance artists for its exceptional brilliance and resistance to fading. Today, synthetic ultramarine is widely available, offering a more affordable alternative while retaining the color's characteristic richness. It is commonly used in paints, inks, and plastics, prized for its stable and vibrant hue. Ultramarine is located in the blue section of the color spectrum, known for its association with depth, stability, and intelligence.

The color #040197, a deep ultramarine, presents significant accessibility challenges. Its very low luminance value of 0.002 means that text rendered in this color requires extremely light foreground colors to meet WCAG (Web Content Accessibility Guidelines) contrast standards. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Given the darkness of ultramarine, only colors approaching pure white will provide sufficient contrast. When using this color for backgrounds, ensure all interactive elements and text have adequate contrast. Providing options for users to adjust color schemes can further enhance accessibility. Also, avoid using this color as the sole means of conveying important information, as users with color vision deficiencies may not be able to distinguish it effectively from other dark shades.
