General Information about #0D222F

The hex color #0D222F, often referred to as "Firefly", is a dark, muted shade of blue-gray. It belongs to the family of cool colors and evokes a sense of calm, sophistication, and depth. In the RGB color model, #0D222F is composed of 5.1% red, 13.33% green, and 18.43% blue. The specific ratio of red, green, and blue light results in a unique hue that appears soft. This color is often used to create a relaxing and somber aesthetic. In terms of its spectral properties, the low saturation and luminance values of #0D222F suggest that it reflects very little light, absorbing most of the incident radiation. The color is a good choice for backgrounds, accents, and other applications where a subtle and understated appearance is desired. However, care should be taken to ensure adequate contrast with other elements in a design, especially text, to maintain readability and accessibility.

The hex color #0D222F, also known as Firefly, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value (dark shade) results in very low contrast against standard white backgrounds. This can make text and other visual elements difficult to read, straining the eyes and potentially causing discomfort. To improve accessibility, it's crucial to pair #0D222F with very light colors that offer a high contrast ratio, ideally exceeding the WCAG (Web Content Accessibility Guidelines) recommended ratios of 4.5:1 for normal text and 3:1 for large text. Using text sizes significantly larger than average can also partially mitigate the contrast issue. Furthermore, avoid using #0D222F for critical interactive elements such as buttons or links without a clear visual indicator beyond color, such as an underline or icon. Consider providing alternative color schemes that offer better contrast for users with low vision or color blindness, ensuring that all users can comfortably access and interact with your content.
