The hex color #000640, also known as Stratos, presents significant accessibility challenges due to its extremely dark nature. When used as a foreground color, it requires a very light background to provide sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal text and 3:1 for large text to meet Level AA compliance. Given its low luminance, #000640 struggles to meet these thresholds with many common background colors. Web developers must carefully select appropriate foreground colors or use color contrast tools to ensure compliance. Using this color for essential UI elements or lengthy text blocks should be avoided unless paired with a very light color to prevent visual fatigue and ensure usability for users with visual impairments. Alternative, lighter shades or tints should be considered to improve accessibility without sacrificing the desired aesthetic.
