General Information about #1B0A8E (Ultramarine)
The hex color #1B0A8E, also known as Ultramarine, is a deep shade of blue that evokes feelings of sophistication, depth, and tranquility. In the RGB color model, it is composed of 10.6% red, 3.9% green, and 55.7% blue. In the CMYK color model, which is often used for printing, it is composed of 81% cyan, 93% magenta, 0% yellow, and 44% black. Ultramarine has a rich history, originally derived from the precious stone lapis lazuli, and was highly valued in art and decoration for centuries. Today, it can be reproduced synthetically, making it more accessible for various applications. Its association with royalty and spirituality makes it a powerful choice for designs aiming to communicate trust and wisdom. Its light reflectance value is very low.
The hex color #1B0A8E, a deep ultramarine, presents accessibility challenges for web design. Its low luminance value (approximately 3) means text rendered in white may barely meet the WCAG AA contrast ratio threshold of 4.5:1 for normal text sizes against this background. Larger text sizes (14pt bold or 18pt regular) will likely meet the minimum contrast requirement, but careful testing is crucial. For optimal accessibility, consider lighter text colors (avoiding pure black) or employing color combinations with high contrast ratios, such as yellows, oranges, or lighter shades of green. Using a color contrast analyzer is highly recommended during the design process to ensure compliance with accessibility standards and to create a more usable experience for individuals with visual impairments. Also consider the color blindness of users when selecting your colors. Check colors with tools.

It's a good choice for websites targeting financial services, educational institutions, or technology companies aiming for a professional look. Ultramarine evokes trust and knowledge, but should be carefully implemented and balanced with more visible hues.
