The hex color #255EC1, also known as Cerulean Blue, presents several accessibility considerations for web developers. Its relatively low lightness value means it may not provide sufficient contrast when used as text against a white background. Therefore, careful attention should be paid to the contrast ratio, ensuring it meets WCAG guidelines (ideally 4.5:1 for normal text and 3:1 for large text). When used as a background color, pairing it with light-colored text like white or very pale yellow can improve readability. Additionally, consider users with color vision deficiencies. Testing the color combination with simulation tools that mimic different types of color blindness is crucial to ensure that important information is still conveyed effectively. Providing alternative visual cues, like underlines or icons, alongside color can also enhance accessibility for all users. When this color is used as focus indicator, make sure that the focus is easily noticable against the background.
