The hex color #1F4EC7, also known as Cerulean Blue, presents some accessibility challenges, particularly when used as a foreground color on a white background. Its luminance value is relatively low, which means the contrast ratio might not meet WCAG (Web Content Accessibility Guidelines) standards for normal text (4.5:1) or large text (3:1). To ensure readability and accessibility, it's crucial to pair Cerulean Blue with a light background color, such as white (#FFFFFF) or a very light gray. Alternatively, using a darker shade of blue or a complementary color like yellow as the background can improve contrast. Designers should always test color combinations using accessibility tools to verify compliance with WCAG guidelines, especially for users with visual impairments. Careful consideration of font size and weight can also mitigate some contrast issues. Remember that color alone should not be used to convey important information; always provide alternative cues such as text labels or icons.
