The color #181B80, also known as Deep Koamaru, presents certain accessibility challenges due to its low lightness value. When used as a foreground color against a white background, it may not provide sufficient contrast for users with visual impairments, potentially failing WCAG standards for contrast ratios. A minimum contrast ratio of 4.5:1 is generally recommended for normal text, and 3:1 for large text. Therefore, when using this color, it's crucial to pair it with very light colors like white (#FFFFFF) or very light grays to ensure readability and accessibility. Consider using accessibility evaluation tools to test the contrast ratio and ensure compliance with accessibility guidelines. Alternatively, using it for decorative purposes or in large graphical elements may mitigate some accessibility concerns, provided essential information is not conveyed solely through this color. When in doubt, prioritize accessibility by opting for higher contrast color combinations.
