General Information about Ultramarine

The color #1A12A2, commonly known as Ultramarine, is a deep, rich shade of blue. It historically derives its name from the pigment produced by grinding lapis lazuli, a semi-precious stone that was imported from overseas ('ultra mare' in Latin). This pigment was highly valued in the Middle Ages and Renaissance, often reserved for painting the robes of the Virgin Mary due to its expense and rarity. In the RGB color model, #1A12A2 consists of 10.2% red, 7.1% green, and 63.5% blue. In the CMYK model, it's composed of 84% cyan, 89% magenta, 0% yellow, and 37% black. Ultramarine is often associated with depth, stability, and intelligence, making it a popular choice for branding and design where a sense of trust and authority is desired. It evokes a sense of calm, intelligence and sophistication.

The color #1A12A2, a deep shade of ultramarine, presents certain accessibility challenges. Its dark nature means it requires careful consideration when used as a background or text color. To ensure readability, it's crucial to pair it with a light, contrasting color such as white, light yellow, or a pale shade of gray. A contrast ratio of at least 4.5:1 is recommended for body text, as specified by WCAG guidelines. For larger text or headings, a ratio of 3:1 may be acceptable. Avoid using this color for interactive elements like buttons or links without sufficient contrast, as users may struggle to identify them. Using a color contrast checker during the design process is helpful. It's also important to consider users with visual impairments who may have difficulty distinguishing between similar dark colors. Therefore, relying solely on color to convey information is not advisable; supplementing it with text or icons is better.
