The color #18404F, a deep, muted blue-green, presents some accessibility challenges. When used as text, it requires careful consideration of contrast ratios against background colors. To ensure readability for users with visual impairments, a light background is strongly recommended. A contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text to meet WCAG AA standards. For enhanced accessibility (WCAG AAA), these ratios increase to 7:1 and 4.5:1 respectively. When used for interactive elements like buttons or links, sufficient contrast should also be maintained for focus states. Providing alternative styling options, such as a high-contrast mode, can further improve accessibility for users with diverse needs. Avoid pairing this color with similar dark hues, as this would significantly reduce legibility. Testing with accessibility tools is recommended.
