General Information about Ultramarine (#1A04B0)

The color #1A04B0, also known as Ultramarine, is a deep and rich shade of blue that falls within the blue-violet spectrum. It is characterized by its strong blue hue with a subtle hint of purple, giving it a sophisticated and elegant appearance. Historically, Ultramarine was derived from the rare and expensive mineral lapis lazuli, making it a highly prized pigment used in paintings and decorative arts. Today, synthetic Ultramarine is widely available, offering the same vibrant color at a more accessible price point. Its hex code is #1A04B0, RGB values are R:26, G:4, B:176, and CMYK values are C:85, M:98, Y:0, K:31. This color evokes feelings of calmness, trust, and authority.

The color #1A04B0, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white background, it falls far short of the WCAG (Web Content Accessibility Guidelines) recommended contrast ratios. This can make the text difficult to read for users with low vision or color blindness. To improve accessibility, consider pairing Ultramarine with much lighter colors, such as whites, light yellows, or pale greens, for text or foreground elements. Conversely, if using it as a background, opt for text colors like white or very light grays to ensure sufficient contrast. Tools like contrast checkers can help determine if the color combinations meet accessibility standards. Implementing these measures can help make your designs more inclusive and usable for everyone.
