General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0C108C, is a deep, rich shade of blue. Historically, ultramarine was derived from the precious stone lapis lazuli, making it one of the most expensive pigments available during the medieval and Renaissance periods. Its name literally means "beyond the sea," referring to its origin from stones imported into Europe from Asia. Today, synthetic ultramarine is widely available, offering a more affordable alternative while retaining the color's distinctive hue. Ultramarine blue is known for its excellent lightfastness and stability, making it a popular choice for artists and designers across various mediums. Its vibrant and intense color evokes feelings of depth, mystery, and sophistication.

The color #0C108C, also known as Ultramarine, presents significant accessibility challenges due to its low luminance value. When used as text, it requires careful consideration of the background color to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Ultramarine's darkness necessitates a very light background to meet these standards. Using it for small text on a dark or moderately colored background would render it nearly illegible for many users, especially those with visual impairments. To improve accessibility, consider using Ultramarine sparingly and pairing it with high-contrast colors. Testing color combinations with accessibility tools is crucial to ensure usability for all users. Also, provide alternative visual cues like icons or labels to convey information instead of relying solely on color.
