The color #1d37c9, also known as Persian Blue, presents some accessibility challenges, particularly when used as a background for text. Its relatively low luminance value of 0.11 means it offers insufficient contrast with lighter text colors like white or even light grays. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with moderate visual impairments. When pairing #1d37c9 with text, careful consideration is needed to ensure sufficient contrast. Using a color contrast checker tool can help verify compliance with accessibility standards. For instance, a very light shade of yellow or a bright white would be better options compared to using light grey. Avoiding smaller font sizes is also important for enhancing legibility. Moreover, it is always important to consider the needs of colorblind users by providing alternative visual cues.
