General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1C05AF, is a deep blue color that evokes feelings of sophistication, depth, and tranquility. It is a color often associated with royalty, wisdom, and stability. In the RGB color model, #1C05AF is composed of 11% red, 2% green, and 69% blue. This significant presence of blue gives the color its characteristic deep hue. Ultramarine's rich and intense nature makes it suitable for applications where a sense of importance and elegance is desired. It is important to note that the perceived brightness and contrast of Ultramarine are relatively low, meaning it should be used thoughtfully in design to ensure readability and accessibility. This color can add a touch of drama when paired with light colors, or a serene, deep atmosphere when matched with other dark shades.

The color #1C05AF, Ultramarine, presents significant accessibility challenges due to its dark nature. When used as a background color, it necessitates very light text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Ultramarine's darkness means many common text colors will not provide adequate contrast. For users with visual impairments, including those with low vision or color blindness, insufficient contrast can render content unreadable. Therefore, it is crucial to carefully select text colors and consider providing alternative high-contrast themes to accommodate diverse user needs. Additionally, avoid using this color for essential information or interactive elements without proper contrast, as it could exclude a significant portion of your audience. Consider using tools to check the contrast ratio and ensure your design is accessible.
