General Information about Firefly (#0A2A3B)

The hex color #0A2A3B, often referred to as Firefly, is a dark, desaturated shade of teal or blue-green. It belongs to the family of cool colors, evoking feelings of calmness, depth, and sophistication. In the RGB color model, it is composed of 3.92% red, 16.47% green, and 23.14% blue. This color is commonly used in graphic design, web development, and interior decoration to convey a sense of professionalism, trustworthiness, or tranquility. Its muted tone makes it versatile for backgrounds, accents, and text elements, although careful consideration of contrast is necessary to ensure accessibility. Because it's a dark color, it is perfect for minimalistic designs or night theming.

The hex color #0A2A3B, also known as Firefly, presents specific accessibility challenges, primarily due to its low luminance. When used as a foreground color against a white background, it may not provide sufficient contrast for users with visual impairments, according to WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Firefly may fail to meet these standards in many scenarios, potentially making content difficult to read. Therefore, when employing this color, it is crucial to pair it with a very light background, like white or a very pale yellow, or use it for larger text elements to improve readability. Ensuring sufficient contrast not only benefits users with disabilities but also enhances the overall user experience for everyone, especially in environments with varying lighting conditions.
