General Information about Blue Charcoal

#030518, commonly referred to as Blue Charcoal, is a very dark shade of blue, nearly approaching black. Its hexadecimal representation indicates a low intensity of red, green, and blue light, resulting in its deep, muted tone. Colors like this are often described as being sophisticated, mysterious, or even somber. In color psychology, dark blues like Blue Charcoal can evoke feelings of calmness, stability, and authority, but can also be associated with sadness or distance. The color's minimal light reflection gives it a subtle, understated presence, making it suitable for applications where a bold statement is not desired but a touch of elegance is appreciated. Its composition makes it challenging to work with in terms of accessibility, requiring careful consideration of contrast with lighter elements.

The hex color #030518, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. Its contrast ratio against standard white (#FFFFFF) is very poor, making text and graphical elements rendered in this color difficult to perceive for users, especially those with visual impairments. To ensure accessibility, it is crucial to pair #030518 with very light or bright colors that provide sufficient contrast. Following WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using tools like contrast checkers can help designers and developers determine if the chosen color combinations meet accessibility standards. Consider alternative, lighter shades if achieving sufficient contrast proves difficult.
