Its relatively low luminance can create insufficient contrast against lighter backgrounds, making text or interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #284FF0 for text, it's advisable to pair it with a very light color like white or a pale yellow to ensure adequate contrast. Similarly, when using it for interactive elements, ensure that hover or focus states provide sufficient contrast changes to be noticeable by all users. Using a color contrast checker tool is highly recommended during the design process to verify compliance with accessibility standards.
