The luminance of the color is very low, which impacts the accessibility.

The color #1505D1, a dark blue, presents several accessibility considerations, especially in web design. Its low luminance value means it requires careful attention to contrast ratios when used for text or interactive elements. 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 #1505D1 as a background, light colors like white or very light shades of yellow or green are advisable for text to ensure readability for users with visual impairments. Conversely, when #1505D1 is used for text, a very light background is necessary. It's crucial to test the color combination with accessibility evaluation tools to meet WCAG compliance. Also, avoid using color as the sole means of conveying information; provide alternative cues like text labels or icons to ensure inclusivity for colorblind users.
