The hex color #1E21B8, also known as Persian Blue, presents some accessibility challenges, particularly in text-based contexts. Due to its relatively low luminance, it offers insufficient contrast against standard white backgrounds (such as #FFFFFF). This lack of contrast can make text difficult to read for users with visual impairments, including those with low vision or color blindness. According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. To improve accessibility, it's advisable to pair #1E21B8 with lighter colors like white, light gray or a very light shade of yellow or green, ensuring the contrast ratio meets accessibility standards. Using contrast checking tools is helpful to evaluate the contrast ratio and determine if adjustments are needed to meet accessibility guidelines.
