General Information about Ultramarine

The hex color #1F0299, also known as Ultramarine, is a deep, rich shade of blue. It belongs to the blue color family, specifically within the range of intense, saturated blues. In the RGB color model, it is composed of 12.2% red, 0.8% green, and 60% blue. This combination results in a color that evokes feelings of depth, sophistication, and tranquility. Ultramarine has historical significance, originally derived from the precious mineral lapis lazuli, making it a highly valued pigment in art for centuries. Its use in paintings and decorative arts symbolized wealth and status. Modernly, the color is synthetically produced, making it more accessible, but it still retains its association with elegance and artistic expression.

The color #1F0299, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value results in poor contrast against common background colors like white, making text and other visual elements difficult to discern. To ensure readability and usability, it's crucial to use this color with a light background that provides sufficient contrast, adhering to WCAG guidelines for contrast ratios. For instance, using a light yellow or a very pale gray as a background could improve accessibility. Additionally, avoid using this color for critical interactive elements without clear visual cues, as users with color blindness may struggle to identify them. Providing alternative text descriptions and using ARIA attributes can further enhance the accessibility of content using this color.
