The hex color #1D50B9, also known as Cerulean Blue, presents certain accessibility considerations. Its relatively dark hue provides a good starting point for text and user interface elements intended to be legible. However, it's crucial to ensure sufficient contrast, especially when pairing it with lighter backgrounds or text colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. When using #1D50B9 as a background, lighter text colors such as white or light grays are preferable. Conversely, when used as a text color, a very light background is necessary. Careful consideration should also be given to users with color vision deficiencies; relying solely on color to convey information is discouraged. Provide alternative visual cues, such as icons or text labels, to ensure usability for all users. Tools for checking color contrast ratios are widely available and should be used to validate the accessibility of color combinations.
