The color #172FB3, also known as Persian Blue, presents some accessibility challenges, particularly in text applications. Its relatively low luminance value of approximately 0.11 does not provide sufficient contrast against light backgrounds like white (#FFFFFF). According to WCAG (Web Content Accessibility Guidelines), a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to ensure readability for users with visual impairments. When using #172FB3 for text, it is crucial to pair it with a very light color (ideally white or a very pale yellow) to meet these contrast requirements. For graphical elements and user interface components, a contrast ratio of 3:1 is generally sufficient. Consider using a color contrast checker tool to verify the contrast ratio between #172FB3 and the background color you intend to use. If sufficient contrast cannot be achieved, it's advisable to choose a different color or use a lighter tint of #172FB3. Remember to also consider users with color vision deficiencies when designing. It may be beneficial to provide alternative color schemes that cater to different types of color blindness.
