The hex color #1e45d9, also known as Cerulean Blue, presents some accessibility challenges, particularly for text-based content. Its relatively low luminance can result in insufficient contrast against light backgrounds, potentially making it difficult for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #1e45d9 for text requires careful consideration of the background color. Lighter shades of yellow, green, or even very light grays might provide adequate contrast. When using this color for interactive elements like buttons or links, ensure sufficient visual cues are present to aid user recognition, such as clear borders or distinct hover states. Consider using color contrast checking tools to verify compliance with accessibility standards and provide a better user experience for everyone.
