The hex color #1B3021, also known as Celtic, presents some accessibility challenges due to its relatively low luminance. When used as a foreground color against a white background, or vice versa, it may not provide sufficient contrast for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color may fall short of these recommendations, making it difficult for some users to read content. To improve accessibility, consider using a lighter background color or a lighter text color to increase the contrast ratio. Tools like WebAIM's contrast checker can help you evaluate the contrast ratio of your color combinations and ensure they meet accessibility standards. Also consider that colorblind users might not perceive the color correctly, so additional visual cues should be provided for important information.
