The hex color #2B46BB, also known as Cerulean Blue, presents some accessibility challenges, especially regarding text contrast. When using this color as a background, it's crucial to pair it with a light text color like white or a very pale yellow to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using a color contrast checker is essential to verify compliance. Avoid pairing Cerulean Blue with darker shades of blue, purple, or grey, as this will likely result in insufficient contrast. For individuals with visual impairments, poor contrast can significantly hinder their ability to perceive and understand content, leading to a frustrating user experience. Thoughtful color choices are paramount to creating inclusive and accessible designs.
