The hex color #2347c3, a deep cerulean blue, presents several accessibility considerations for web developers. Its relatively low lightness value means it requires careful contrast management, especially for text. When used as a background color, it's crucial to pair it with light-colored text (white or very light grays) to meet WCAG guidelines for contrast ratios (minimum 4.5:1 for normal text and 3:1 for large text). Avoid using #2347c3 for small text or icons on dark backgrounds, as this can cause readability issues for users with visual impairments. Tools like contrast checkers can help verify sufficient contrast. Consider providing alternative color schemes or user-adjustable contrast settings to accommodate diverse user needs. Providing proper ARIA labels for interactive elements is always advised. The color's strong blue hue may also pose challenges for individuals with certain types of color blindness; thus, relying solely on this color to convey important information should be avoided.
