General Information about #0A00B4

#0A00B4 is a hexadecimal color code representing a dark shade of blue. In the RGB color model, it is composed of 3.92% red, 0% green, and 70.59% blue. This significant disparity in RGB values results in a deep, saturated blue hue. Hex color codes are commonly used in web design and graphic design to specify colors precisely. The color can be displayed on computer screens and other electronic devices with ease. The color #0A00B4 is often associated with feelings of trust, stability, and authority. Its use can also suggest sophistication and knowledge. However, due to its darkness, it is not suitable for all applications and must be used carefully to ensure readability and accessibility, especially in textual contexts.

The color #0A00B4, a dark blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value means that text rendered in this color requires very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using white or very light shades of yellow or green as foreground colors can help achieve the necessary contrast. Moreover, it's crucial to avoid using this color for essential interactive elements without clear visual cues and labels, as users with color blindness might struggle to perceive them. Proper testing with accessibility evaluation tools and real user feedback is essential to ensure that content using #0A00B4 is accessible to everyone.
