#310300

General Information

#310300, also known as Sepia Black, is a very dark, muted shade of brown. In the RGB color model, it's composed of 19.22% red, 1.18% green, and 0% blue. Represented in the HSV (or HSB) model, it has a hue angle of 9 degrees, a saturation of 100%, and a brightness of 19.2%. This color tends to evoke feelings of antiquity, earthiness, and understated luxury. Its darkness suggests that it might be challenging to use as a primary color without careful consideration of contrast and readability.

The hex color #310300, also known as Sepia Black, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of 0.004 makes it difficult to distinguish from black (#000000). The contrast ratio against white (#FFFFFF) is a mere 5.27:1, falling short of the WCAG's minimum requirement of 4.5:1 for normal text and 3:1 for large text. Using this color for text or interactive elements without careful consideration will likely create a poor user experience and exclude many users. To improve accessibility, consider using lighter colors for text on a #310300 background or vice versa. Thoroughly test color combinations with accessibility tools to ensure sufficient contrast and readability.
