The color is close to pure blue, leaning toward the darker end of the spectrum.

The hex color #0303E3, a very dark blue, presents significant accessibility challenges. Its extremely low luminance value means that text rendered in this color against a white background, or even a light-colored background, will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. This is particularly crucial for users with visual impairments who rely on sufficient contrast to distinguish text from the background. To ensure accessibility, it is imperative to use #0303E3 sparingly, if at all, for text. When it is necessary, a very light color, such as white (#FFFFFF) or a pale yellow, should be used for the text to ensure sufficient contrast. Tools like contrast checkers can help verify compliance with accessibility standards. Additionally, consider providing alternative styling options or themes that offer higher contrast for users who need it.
