It's important to note that due to its low lightness value, careful consideration should be given to its accessibility when used in textual contexts.

The hex color #0645AD, also known as Cobalt, presents some accessibility challenges, especially when used as a foreground color. Its low lightness value (approximately 15%) means that it requires a very light background color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using Cobalt for text, designers should prioritize pairing it with colors like white (#FFFFFF) or very light shades of gray to meet these contrast requirements. Using darker background colors can make text illegible for users, particularly those with visual impairments. Additionally, avoid using Cobalt for small, intricate details or icons where clarity is essential. Providing alternative color schemes or allowing users to customize the color settings can enhance accessibility for a broader audience.
