About Hex Color #0A2AAA
The hexadecimal color #0A2AAA represents a deep and vibrant shade of blue, often associated with the International Klein Blue (IKB). IKB was developed by the French artist Yves Klein. In the RGB color model, #0A2AAA is composed of 3.92% red, 16.67% green, and 66.67% blue. This color is relatively dark, with a low luminance value, contributing to its intense and saturated appearance. In the context of color theory, this specific shade of blue can evoke feelings of calmness, depth, and sophistication. Due to its unique hue, it is often used to convey a sense of trust, stability, and authority. It is important to note that the visual perception of this color can vary depending on the display device and ambient lighting conditions.
The hex color #0A2AAA, a deep, vibrant blue reminiscent of International Klein Blue, presents several accessibility considerations for web developers. Its relatively low luminance value means it requires careful pairing with contrasting colors to ensure readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #0A2AAA as a background, light colors like white, light grey, or pale yellow should be employed for text to meet these contrast requirements. Conversely, using dark text on a #0A2AAA background could render the text illegible for many users. Developers should use contrast checking tools to verify compliance. It's crucial to avoid using this color for conveying critical information without proper contrast, as this would exclude a significant portion of users. Additionally, consider providing alternative color schemes to accommodate users with specific visual preferences or needs.
