The hex color #2947BC, also known as Cerulean Blue, presents some accessibility considerations for web development. Its relatively low luminance (a measure of perceived brightness) can pose challenges when selecting text colors for optimal contrast. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #2947BC as a background, a light text color such as white or a very pale yellow should be considered to ensure adequate contrast. Tools are available to calculate the contrast ratio between two colors, allowing developers to verify compliance with accessibility standards. Careful selection of text color will ensure that content is accessible to a wider audience.
