General Information About #101821

The hex color #101821, often referred to as Vulcan, is a very dark shade of grayish brown. In the RGB color model, it consists of 6.27% red, 9.41% green, and 12.94% blue. Its primary use is in situations that call for a subdued or understated aesthetic. Vulcan conveys feelings of seriousness, sophistication, and quiet strength. It is frequently used in design contexts where a neutral or grounding element is needed. Given its low brightness and saturation, #101821 is best utilized as an accent color or a background element rather than for primary text or interactive components because of its accessibility implications. Subdued color schemes and minimalist designs are appropriate for this color.

The hex color #101821, also known as Vulcan, presents significant accessibility challenges due to its dark nature. Its low luminance results in poor contrast against lighter backgrounds, making it difficult for users with visual impairments to perceive text or graphics. According to WCAG guidelines, sufficient contrast is essential for readability. Therefore, when using #101821, it is crucial to pair it with a very light color for text or interactive elements to ensure compliance with accessibility standards. Using contrast checking tools is highly recommended to verify that the chosen color combinations meet the minimum contrast ratios specified by WCAG, typically 4.5:1 for normal text and 3:1 for large text. Failing to meet these ratios can exclude a significant portion of users from accessing the content effectively. Consideration should also be given to users with color blindness, as certain color combinations may further reduce visibility.
