The hex color #1B0A91, also known as Ultramarine, is a deep, saturated shade of blue with a hint of violet. It belongs to the blue color family and is composed of 10.6% red, 3.9% green, and 56.9% blue in the RGB color model. In the CMYK color model, used for printing, it consists of 81% cyan, 93% magenta, 0% yellow, and 43% black. This color is often associated with depth, stability, and confidence. It is a non-process color, meaning it cannot be accurately reproduced using only the standard cyan, magenta, yellow, and black inks. Ultramarine's rich and intense hue makes it suitable for a variety of applications, from digital design to fashion. Its unique characteristics and evocative associations contribute to its enduring popularity across different creative fields.
The color #1B0A91, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 3% means that text rendered in this color against a white background fails WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. To ensure readability and usability, especially for users with low vision or color blindness, it is crucial to use a light color for text when #1B0A91 is used as a background. White (#FFFFFF) or a very light gray would be suitable choices. Additionally, avoid using this color for essential interactive elements, such as buttons or links, without clear visual cues like borders or icons. Consider providing alternative color schemes or themes that offer higher contrast for users who need them. Tools such as accessibility checkers can help evaluate and improve the contrast ratios in designs using this color, creating a more inclusive and accessible experience for all users.
