The hex color #284BBE, also known as Cerulean Blue, presents some accessibility challenges primarily due to its relatively low luminance. When used as a foreground color against a white background, it may not provide sufficient contrast for users with visual impairments, making it difficult for them to read text or discern important visual elements. 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, necessitating the use of alternative, lighter background colors or adjustments to the text size and weight to improve readability. Using a color contrast checker is advisable to ensure compliance with accessibility standards and provide an inclusive experience for all users.
