Ultramarine

#011497

General Information about Ultramarine

The color #011497, also known as Ultramarine, is a deep, saturated shade of blue. Ultramarine's name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally derived from the precious mineral lapis lazuli, imported from faraway lands. This color has historically been highly valued and used in art, particularly during the Renaissance, where it symbolized royalty and divinity due to its rarity and expense. Chemically synthesized ultramarine became available in the 19th century, making it more accessible for wider use. In modern applications, Ultramarine conveys a sense of stability, trust, and authority, often used in corporate branding and web design. Its rich hue can also be found in paints, inks, and dyes.

The color #011497, a deep ultramarine, presents several accessibility considerations for web development. Its low luminance value means it requires careful pairing with text and other visual elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #011497 as a background, ensure that any foreground text is light enough to meet these contrast requirements. White or very light shades of yellow or green could work well. Furthermore, avoid using this color as the sole means of conveying information, as users with color vision deficiencies may struggle to differentiate it from other dark colors. Always provide alternative cues, such as text labels or icons, to ensure inclusivity. Testing with accessibility tools is crucial to validate the contrast ratios and overall accessibility of your design when incorporating such a deep hue.
