#030C17

General Information about Blue Charcoal

The color #030C17, commonly known as Blue Charcoal, is a very dark shade of blue, almost approaching black. It has a subtle, muted quality, reminiscent of the dark depths of the ocean or a night sky. In the RGB color model, it is composed of 1.2% red, 4.71% green, and 9.02% blue. This composition gives it a cool, calming feel. Because of its low lightness value, this color is often perceived as sophisticated, mysterious, and understated. It's a versatile color that can be used in various applications to create a sense of depth and elegance. However, its darkness also means that it should be used with care, especially when considering accessibility, as it can be difficult to see against darker backgrounds.

The hex color #030C17, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text and user interface design. Its extremely low luminance value results in very poor contrast against white or light backgrounds, making it difficult for users with visual impairments to read text or discern interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #030C17 falls far short of these recommendations when paired with typical background colors. To improve accessibility, consider using this color sparingly and always ensure sufficient contrast by pairing it with much lighter colors. Alternatively, use color contrast tools to evaluate and adjust the color combination until it meets accessibility standards, thereby creating a more inclusive user experience. Avoid relying solely on color to convey critical information, and provide alternative cues such as text labels or icons.
