Its subtle blue undertone adds a touch of calmness and serenity to any design.

The hex color #04101A, also known as Blue Charcoal, presents significant accessibility challenges due to its very dark nature. When used as a background color, it requires extremely light text to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Blue Charcoal often fails to meet these standards unless paired with colors that are very close to white. Therefore, designers and developers should carefully evaluate the color pairings to avoid creating barriers for users with visual impairments. Consider using online contrast checkers to verify compliance and explore alternative, lighter shades if necessary. Ensuring adequate contrast is crucial for maintaining an inclusive and accessible web experience.
