General Information about Nero (#170405)

The hex color #170405, often referred to as Nero due to its near-black appearance, is a very dark shade of brown. It consists of 9.02% red, 1.57% green, and 1.96% blue. In the RGB color space, it has values of R:23, G:4, B:5. In the CMYK color space, the values are C:0, M:0.83, Y:0.78, K:0.91. The hue angle is 354.3 degrees, the saturation is 81.6%, and the lightness is 5.5%. Because of its darkness, it's used for creating depth and contrast in design. The low values on the green and blue spectrum lead to a color close to black but with a hint of red, giving it a subtle warmth that differentiates it from pure black. This color is often used in combination with lighter colors to achieve visually appealing designs.

The hex color #170405, also known as Nero, presents significant accessibility challenges due to its extremely dark nature. Its very low luminance results in poor contrast against lighter backgrounds, making it difficult for individuals with visual impairments to perceive text or graphical elements rendered in this color. Web Content Accessibility Guidelines (WCAG) emphasize a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text to ensure readability. Nero falls far short of these recommendations. Therefore, it's crucial to avoid using Nero for text or important interface elements unless paired with a very light color to achieve an acceptable contrast ratio. Careful consideration and testing with accessibility tools are essential to ensure that content using this color is perceivable and usable by all users, including those with low vision or color deficiencies. Using Nero as a background color with white or very light text is one way to improve accessibility.
