The hex color code #180F17, often referred to as 'Cinder', is a very dark, muted shade of purple. It belongs to the family of near-black colors, characterized by low saturation and luminance values. In the RGB color model, it consists of 9.41% red, 5.88% green, and 8.63% blue. This color is commonly used in design projects where a subtle, understated tone is desired. Its hex triplet is #180F17, and it can be represented in other color models such as CMYK (0%, 37%, 8%, 90%) or HSL (309 degrees, 23% saturation, 8% lightness). Because of its darkness, care should be taken to ensure that the color does not cause any accessibility issues.

The hex color #180F17, also known as Cinder, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 2.2 cd/m² results in poor contrast against both white and black backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability. This color falls far short of meeting these standards, making text rendered in #180F17 difficult to read for many users. To improve accessibility, consider using a lighter color for the foreground text or a darker background color to increase the contrast ratio. Tools like WebAIM's Contrast Checker can help you evaluate and adjust color combinations to meet accessibility requirements, ensuring a more inclusive user experience.
