The color #021BE4, a deep and vibrant blue, presents significant accessibility challenges. Its low luminance value of approximately 2% means that it offers very little contrast when used against a standard white background. This lack of contrast can make text or graphical elements difficult, if not impossible, for users with visual impairments to discern. 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 to meet Level AA compliance. This blue falls far short of these requirements. To improve accessibility, it is crucial to pair this blue with much lighter colors, such as white or pale yellows, to achieve an adequate contrast ratio. Alternatively, using a darker shade for the background or using a larger font size and heavier font weight could also enhance readability for users with low vision. Careful consideration of color combinations is paramount to ensure an inclusive and user-friendly experience for all website visitors.
