The color #173FB3, a deep Persian Blue, presents some accessibility challenges, especially when used as a background or text color. Its luminance is relatively low, meaning that careful consideration must be given to the contrast ratio against foreground or background elements. For text, it's crucial to ensure a contrast ratio of at least 4.5:1 against smaller text and 3:1 against larger text (14pt bold or 18pt regular) to comply with WCAG 2.1 AA standards. When used for interactive elements like buttons or links, additional visual cues beyond color alone should be provided to ensure usability for users with color vision deficiencies. For instance, using underlines for links or providing icons alongside text can significantly improve accessibility. Testing the color combination with accessibility tools is recommended to verify compliance and ensure a positive user experience for everyone, including those with visual impairments.
