The color #1D28B9, also known as Persian Blue, presents certain accessibility challenges, especially when used as a foreground color against a background color close to it in luminance. Its relatively low luminance value means that text rendered in this color may be difficult to read for users with visual impairments. Ensuring sufficient contrast is crucial for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using Persian Blue, it's essential to pair it with a light background to meet these contrast requirements. Tools are available to check contrast ratios and ensure accessibility compliance. Additionally, consider providing alternative color schemes that offer better contrast for users who may need them. The color should not be used to convey important information without an additional visual cue, as color blindness affects a significant portion of the population.
