In the RGB color model, it consists of 16.1% red, 4.3% green, and 66.3% blue. This color evokes feelings of sophistication, depth, and perhaps a touch of mystery.

The color #280BA9, a deep blue-violet hue, presents specific accessibility challenges, particularly in web design. Its low luminance value necessitates careful consideration of color contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, sufficient contrast between text and background is crucial. For normal text (size 14 point or 18 point bold), a contrast ratio of 4.5:1 is recommended, while for large text (size 18 point or 14 point bold), a ratio of 3:1 is required. When using #280BA9 for text, a light color like white or a pale yellow is recommended as a background to ensure these contrast ratios are met. If using #280BA9 as a background, light-colored text is similarly required. Tools are available to check the contrast ratio between foreground and background colors, like webaim.org/resources/contrastchecker/.
