The color #2801B3, a deep and vibrant blue, presents some accessibility challenges, particularly regarding color contrast. When used as a background color, it's crucial to pair it with text that has sufficient luminance contrast to ensure readability for users with visual impairments. 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. White or light yellow text would generally work well. It's important to avoid using this color with darker shades of text, as the contrast would likely be insufficient, rendering the text difficult to read. Also, avoid using it to display important information without additional cues. Use colourblindness tools to check the effectiveness of your colour scheme.
