Conversely, using black or other dark colors as text on a Cerulean Blue background would result in poor contrast and make the text difficult to read, potentially causing eye strain and accessibility issues for users with visual impairments. It is crucial to adhere to WCAG (Web Content Accessibility Guidelines) standards, ensuring a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools are available online to check color contrast ratios to help designers make informed decisions. Also be mindful of users with color blindness, and use other visual cues in addition to color to convey important information.
