Blue Charcoal

#02121A

General Information about #02121A

The hex color #02121A, often referred to as Blue Charcoal, is a very dark shade of blue-gray. It sits at the very low end of the luminance scale, indicating its relative darkness. In the RGB color model, it is composed of 2/255 red, 18/255 green, and 26/255 blue. This composition results in a color that is perceived as muted and subdued. The color is often associated with sophistication, elegance, and a sense of depth. Due to its low brightness, it's commonly used in applications where a subtle and understated background is desired. However, its very dark nature also means that it needs to be used carefully in design, with considerations for contrast and accessibility to ensure readability and visibility of foreground elements. The color evokes a sense of calm and reserve, making it suitable for professional or formal contexts.

The hex color #02121A, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. Its contrast ratio against a standard white background (e.g., #FFFFFF) is very poor, making it difficult for users with visual impairments to perceive text or graphical elements rendered in this color. Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Blue Charcoal falls far short of these recommendations. Therefore, using #02121A as a primary text or background color without careful consideration of contrast is strongly discouraged. To improve accessibility, consider pairing it with much lighter colors or using it sparingly for purely decorative elements. Ensure sufficient contrast is maintained with foreground elements to meet accessibility standards and provide a better user experience for everyone, including those with low vision or color blindness. Testing with accessibility tools is crucial.
