General Information

Ultramarine, represented by the hexadecimal color code #1315A1, is a deep, vivid blue hue. It is derived from the pigment lapis lazuli, a semi-precious stone prized since antiquity for its intense color. In the RGB color model, #1315A1 is composed of 7.45% red, 8.24% green, and 63.14% blue. This significant blue component gives Ultramarine its characteristic depth and richness. The term 'Ultramarine' literally means 'beyond the sea,' reflecting the historical origins of the pigment, which was imported to Europe from mines in Asia. Because of the vibrant nature of Ultramarine, it has been a color widely used in the field of art. It is less commonly found in nature.

The color #1315A1, also known as Ultramarine, presents accessibility challenges due to its dark hue. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. It's crucial to test color combinations using accessibility tools to verify compliance. When #1315A1 is used for text, a light background is essential. Thoughtful consideration of colorblindness is also important, as individuals with visual impairments may perceive the color differently. Avoid using color alone to convey important information; supplement with text or icons.
