In color theory, Blue Charcoal can evoke feelings of calmness and stability, while also conveying a sense of seriousness and depth. Its near-black quality makes it a versatile color for backgrounds and accents, but it requires careful consideration of contrast to ensure readability and accessibility.

The hex color #040D16, also known as Blue Charcoal, presents significant accessibility challenges due to its low luminance. Its dark nature results in very low contrast against typical light backgrounds, making it difficult for individuals with visual impairments to discern text or graphical elements. According to WCAG guidelines, this color would likely fail many contrast ratio tests, especially for small text or icons. To improve accessibility, it is essential to pair #040D16 with much lighter colors, ensuring a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using tools to check contrast ratios is highly recommended during the design process to guarantee compliance with accessibility standards and ensure usability for all users.
