General Information about #251B1C (Oil)

The hex color #251B1C, often referred to as "Oil," is a very dark, muted shade of brown. It belongs to the earth tone family and possesses a low saturation level. In the RGB color model, it is composed of 14.51% red, 10.59% green, and 11.0% blue. In the CMYK color model, which is used in printing, it is made up of 0% cyan, 27% magenta, 24% yellow, and 85% black. This color's hexadecimal value translates to a dark and subtle presence, often evoking feelings of sophistication, stability, and earthiness. Due to its low luminance, it is generally used sparingly as a primary color, but it can be effective as an accent color to provide depth and contrast to other hues. In various creative applications, Oil can bring a sense of grounding and refinement.

The hex color #251b1c, also known as Oil, presents significant accessibility challenges, particularly in text and user interface design. Its very low luminance value results in poor contrast against both white and light backgrounds, making it difficult for users with visual impairments to discern text or interactive elements. Adhering to WCAG guidelines is crucial when using this color. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #251b1c for text on a white background would fall far short of this standard. To improve accessibility, it should be paired with very light or vibrant colors for sufficient contrast. Consider avoiding it altogether for critical elements like buttons and links, opting for colors with higher luminance and better contrast ratios to ensure inclusivity.
