Description:
I'd like to contribute to Joomla CMS by enhancing the accessibility of form validation messages. Currently, Joomla’s validation feedback relies heavily on color, which may not be fully accessible to visually impaired users or those with color blindness. This enhancement would improve accessibility by ensuring validation messages are properly announced and distinguishable through multiple indicators.

Proposed improvements:

Add ARIA attributes (aria-live="polite") to validation messages for better screen reader support.
Include icons or textual indicators alongside color changes for better visual distinction.
Improve contrast levels in validation messages for easier readability.
Why this matters:
Accessibility compliance (WCAG) is essential for making Joomla more inclusive. Enhancing validation feedback will improve usability for users who rely on screen readers or have difficulty distinguishing colors. This change ensures Joomla’s forms remain user-friendly across diverse audiences.

Implementation approach:

Modify form templates to include ARIA attributes in error messages.
Updating the CSS to provide sufficient contrast and optional icons in validation messages.
Ensuring validation messages can be understood without relying on color alone.
