#280703

General Information about Sepia Black

The hex color code #280703 represents a very dark shade of reddish-brown, often referred to as Sepia Black. It is composed of 15.7% red, 2.7% green, and 1.2% blue. In the RGB color space, it's quite muted and leans heavily towards the red end of the spectrum, resulting in its deep, earthy tone. The low values across all color channels contribute to its darkness. Colors like this are frequently used to evoke feelings of warmth, nostalgia, or antiquity. In practical applications, the low brightness of this color means it should be used cautiously, particularly when contrast is essential. The color is more frequently used for background tints than for the primary foreground element, such as text.

The color #280703, also known as Sepia Black, presents significant accessibility challenges, especially in web design. Its extremely dark hue results in very low contrast against typical light backgrounds, making text or interface elements nearly illegible for many users. Individuals with visual impairments, including those with low vision or color blindness, will find it particularly difficult to distinguish content using this color. To ensure accessibility, it is crucial to avoid using #280703 for text or interactive elements on light backgrounds. If it is essential to incorporate this color, pair it with a very light color (e.g., white or a very pale yellow) to achieve a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards, aiming for a contrast ratio of at least 4.5:1 for regular text and 3:1 for large text. Thoroughly testing the color combination with accessibility tools is highly recommended to prevent usability issues and ensure an inclusive user experience. Also consider providing alternative high-contrast themes or color options.
