It falls within the range of cool colors and evokes feelings of calmness, sophistication, and depth. The hex code #00121C translates to RGB values of (0, 18, 28). Its CMYK values are approximately 100% cyan, 36% magenta, 0% yellow, and 89% black. In terms of color theory, Blue Charcoal is often associated with stability and trustworthiness, making it a popular choice for corporate branding and professional designs. Due to its dark nature, it is frequently used as a background color or accent color to provide contrast and highlight other elements in a design.

The hex color #00121C, also known as Blue Charcoal, presents several accessibility considerations. Its low luminance value results in a poor contrast ratio against standard white text, making it difficult for users with visual impairments to read. 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 fails to meet these standards when paired with white. To improve accessibility, consider using a lighter text color such as white tints and shades. Avoid using #00121C for critical interactive elements without careful consideration of contrast. Using #00121C on dark backgrounds is not recommended. For users with color blindness, the dark blue hue may be difficult to distinguish from other dark colors, particularly dark grays or blacks. Designers should use colorblindness simulators during development to ensure content remains accessible to all users. Also consider the usage of icons and fonts to improve the UX and accessibility.
