Its relatively low luminance can create insufficient contrast when paired with lighter colors, making text difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #121AD4 as a background, it's crucial to choose a text color that provides adequate contrast. White or very light shades of yellow or green might be suitable options. Tools like contrast checkers can help ensure compliance with accessibility standards. Also, avoid using this color as the sole indicator of important interactive elements, as users with color blindness may not perceive it. Providing additional cues, such as labels or icons, is crucial for ensuring inclusive design.
