General Information about Ultramarine (#1B0296)

The hex color #1B0296, also known as Ultramarine, is a deep and intense shade of blue. It belongs to the blue color family and is characterized by its strong, saturated hue. In the RGB color model, #1B0296 consists of 10.6% red, 0.8% green, and 58.8% blue. This combination results in a color that is both rich and mysterious. Ultramarine has a long history, originally derived from the mineral lapis lazuli, making it a highly prized pigment in art and decoration. Today, synthetic ultramarine is widely available, offering a more accessible option for artists and designers. Its deep blue shade evokes feelings of calmness, sophistication, and trustworthiness. In web design, #1B0296 can be used as a bold accent color or as part of a sophisticated color palette. Due to its darkness, it is crucial to ensure sufficient contrast when using it for text or interactive elements to maintain accessibility.

The hex color #1B0296, a deep shade of ultramarine, presents significant accessibility challenges. Its low luminance value necessitates careful consideration of color contrast ratios, particularly when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against a background. Using #1B0296 on a white background falls far short of these recommendations, potentially causing readability issues for users with visual impairments. To improve accessibility, consider using a much lighter color for text or interactive elements placed on a #1B0296 background. Tools like contrast checkers can help to determine whether specific color pairings meet accessibility standards. Alternatively, applying a color overlay or adjusting the opacity can also enhance readability while maintaining the desired aesthetic. Avoid using #1B0296 for critical information or interactive elements without sufficient contrast, as this can exclude users and create a frustrating experience.
