The color #1815D1, a deep, dark blue, presents several accessibility considerations for web developers. Due to its low luminance, it's crucial to ensure sufficient contrast against background colors, especially for text.

Using this color for essential UI elements like buttons or links necessitates careful attention to affordance cues beyond just color, as users with color vision deficiencies may struggle to distinguish them.

Furthermore, providing alternative visual cues, such as underlines for links or icons for buttons, can enhance accessibility for a broader audience.
