General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #10019A, is a deep blue color with a rich history. The term "ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from mines in Afghanistan by sea. Historically, ultramarine was derived from the semi-precious stone lapis lazuli, making it one of the most expensive and highly prized pigments used by Renaissance artists. Its intense blue hue was often associated with royalty and divinity. In modern times, synthetic ultramarine is readily available, making it more accessible for various applications. In the RGB color model, #10019A is composed of 6.27% red, 0.39% green, and 60.39% blue. This color evokes feelings of calmness, trust, and authority, making it suitable for branding and design purposes where these qualities are desired.

The color #10019A, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a low luminance value, meaning it requires careful pairing with text and background colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. When using #10019A as a background, it's essential to use light-colored text to meet these contrast requirements. Moreover, consider users with visual impairments who may have difficulty distinguishing between subtle color differences. Provide alternative visual cues, such as underlines or icons, to convey information effectively. Avoid using color alone to indicate crucial information, as this can exclude users with color blindness. Thoroughly test the color combination with accessibility tools to guarantee compliance and optimal user experience for all individuals.
