The color #0d148b, a deep, saturated blue, presents some accessibility challenges, especially when used as a background or text color. Due to its low luminance, it requires careful consideration of contrast ratios. When used as a background, it's crucial to pair it with a light text color, such as white or a very pale yellow, to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) AA or AAA standards. Conversely, if used as a text color, it should be placed against a light background. Using color contrast tools to verify the contrast ratio is highly recommended. Avoid pairing it with other dark or similarly saturated colors as this can lead to visual strain and difficulty in distinguishing elements. Meaning should not be conveyed through color alone; supplement with text or other visual cues. Testing with users who have visual impairments is beneficial.
