The color #1535B5, also known as Persian Blue, presents some accessibility challenges, especially concerning text legibility. Due to its relatively low luminance, using it as a background color for light text can result in insufficient contrast, making the text difficult to read for individuals with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA guidelines. When using #1535B5, it's essential to pair it with a very light color, such as white or a pale yellow, to ensure adequate contrast. Using a color contrast checker is highly recommended to verify that the contrast ratio meets accessibility standards. Additionally, avoid using this color for essential interactive elements like buttons or links without careful consideration of the overall contrast and visual clarity. Remember to test your design with different color vision deficiencies to ensure inclusivity.
