General Information about Graphite (#28180A)

The hex color #28180A, also known as Graphite, is a very dark shade of brown. It belongs to the earth tone family and evokes feelings of warmth, stability, and sophistication. In the RGB color model, it is composed of 16.08% red, 9.41% green, and 3.92% blue. This color is often associated with natural materials like wood, soil, and stone, which contributes to its grounding and comforting qualities. Its dark nature makes it a suitable choice for creating subtle accents, or providing a grounding element. However, due to its low luminance, it should be used carefully in designs to ensure sufficient contrast and readability, especially in digital interfaces and printed materials.

The hex color #28180A, a very dark shade of brown, presents significant accessibility challenges, particularly in text-based applications. Its low luminance necessitates careful consideration of contrast ratios to ensure readability 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 against its background. Using #28180A for text requires a very light background color to meet these standards. Designers should use contrast checking tools to verify compliance. When using this color for interactive elements, such as buttons or links, sufficient visual cues beyond color alone are essential, as color blindness affects a significant portion of the population. Providing alternative indicators, like underlines, borders, or icons, will enhance usability for all users. Consider also the context of use; for purely decorative elements, the contrast requirements might be less stringent, but for anything conveying information, adhere to the guidelines.
