The hex color #28505E, also known as Spectra, presents some accessibility considerations. Its relatively low luminance can pose challenges for users with visual impairments. When using this color for text, it's crucial to ensure a sufficiently high contrast ratio against the background. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. For WCAG AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. Tools like contrast checkers can help verify compliance. Additionally, avoid relying solely on color to convey important information, as colorblind users may not be able to distinguish it effectively. Supplement color cues with text labels, icons, or other visual indicators to ensure inclusivity and universal usability.
