General Information about Ultramarine (#1A0A8E)

The color #1A0A8E, commonly known as Ultramarine, is a deep and intense shade of blue that falls within the blue-violet spectrum. Historically, ultramarine was derived from the rare and expensive mineral lapis lazuli, making it a highly prized pigment used by Renaissance painters for its rich and vibrant hue. Today, synthetic ultramarine is readily available, offering the same brilliant color at a more accessible price point. In color psychology, ultramarine is associated with qualities such as wisdom, intelligence, stability, and trust. It often evokes feelings of calmness, serenity, and depth. This color is frequently employed in branding and design to convey reliability, authority, and sophistication. Its intense pigmentation makes it suitable for various applications, from digital interfaces to fine art.

The color #1A0A8E, a deep ultramarine, presents some accessibility challenges, particularly in text-based applications. Due to its low luminance, it requires careful consideration of color contrast ratios. When used as a background color, it is crucial to pair it with a very light foreground color, such as white or a pale yellow, to ensure sufficient contrast for readability, ideally aiming for a contrast ratio of at least 4.5:1 as recommended by WCAG guidelines. For smaller text sizes, even higher contrast ratios might be necessary. Avoid pairing this color with dark or similarly toned colors as it will result in poor readability and a frustrating user experience. In graphical interfaces, ensure that interactive elements using this color are clearly distinguishable through additional visual cues, such as borders or icons, to aid users with visual impairments. Consider using color contrast checking tools during development to verify the accessibility of color combinations.
