About Ultramarine

Ultramarine, represented by the hexadecimal color code #140FA5, is a deep, vivid blue color reminiscent of the pigment derived from lapis lazuli. Its name originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was initially imported to Europe from mines in Asia. Historically, ultramarine was highly prized, even more valuable than gold in some instances, due to its scarcity and the labor-intensive process of extracting it from lapis lazuli. Today, synthetic ultramarine is widely available, making it an accessible color choice for various applications. In color theory, ultramarine is considered a primary color in the RGB color model, forming the base for countless other shades and hues.

The hex color #140fa5, also known as Ultramarine, presents some accessibility challenges, particularly in text-based contexts. Its relatively low luminance value of approximately 10 means it requires careful consideration of contrast ratios. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. When using #140fa5 for text, it's imperative to pair it with a light background to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Moreover, avoid using this color as the sole means of conveying information, as colorblind users may struggle to differentiate it from similar shades. Supplement color cues with text labels or icons to ensure inclusivity and a positive user experience for all users.
