The color #1A4FCC, a deep cerulean blue, presents some accessibility challenges, particularly in text applications. Due to its relatively low luminance, it may not provide sufficient contrast against lighter backgrounds like white or light gray. This can make text difficult to read for users with visual impairments, including those with low vision or color blindness. According to WCAG guidelines, sufficient contrast is crucial for readability. When using #1A4FCC for text, it's important to ensure a contrast ratio of at least 4.5:1 against the background.

It is always advisable to test color combinations with accessibility tools to ensure compliance and optimal readability for all users. Also, consider providing alternative color schemes to accomodate different user preferences.
