General Information about Blue Charcoal

The hexadecimal color code #04131B represents a dark, muted shade of blue, often referred to as Blue Charcoal. In the RGB color model, it is composed of 4/255 red (1.57%), 19/255 green (7.45%), and 27/255 blue (10.59%). This color resides in the lower end of the luminance spectrum, resulting in its dark appearance. Commonly used in digital design and art, Blue Charcoal evokes feelings of sophistication, depth, and calmness. Due to its low saturation and brightness, it can serve as a versatile background or accent color, especially when paired with brighter or lighter hues to create contrast and visual interest. It is important to evaluate the accessibility of this color, because low luminance differences can lead to problems.

The color #04131B, also known as Blue Charcoal, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white or light-colored background, the very low luminance difference results in poor readability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Blue Charcoal fails to meet these thresholds, making it difficult for many users to distinguish text from the background. To improve accessibility, consider using a lighter color for text or a much darker background to create sufficient contrast. Tools like contrast checkers can help evaluate and adjust color combinations to ensure compliance with accessibility standards, promoting inclusivity and usability for all users.
