Input fields on the WordPress admin screens have been nearly invisible since version 2.7. The problem was so severe that Matt suggested I make a plugin to override core CSS values for anyone who wanted more contrast. Following community feedback, I created this extra plugin specifically for high contrast.
This plugin adds Admin Color Scheme options that dramatically change the appearance of form fields, table rows, and background colors in the admin pages. It is not intended to follow the design principles of the built-in style sheets. If this is too much for your needs, then also consider my plugin with more subtle effects called <a href="https://wordpress.org/plugins/fix-admin-contrast/" rel="ugc">Fix Admin Contrast</a>

High Contrast Admin

Adds admin color schemes for the visually impaired.

AxesWeb Accessibility Solution adds an accessibility toolbar to your WordPress site to help users customize their reading experience, in line with WCAG 2.1 and 2.2 guidelines. The widget is lightweight, configurable from the settings page, and designed to be theme-agnostic.
<h3>External services</h3>
This plugin connects to the AxesWeb CDN to load the accessibility widget JavaScript. It is required to render the accessibility UI and features in the front‑end.
What data is sent and when: 
– When the widget is loaded, the browser requests the script file from the CDN. No personal data is sent by the plugin to AxesWeb. The plugin does not add cookies or tracking. 
– When the optional accessibility feedback form is enabled, submissions are sent to your WordPress site via admin-ajax.php using a nonce-protected action. Emails are dispatched by your site to the recipient you configure. No data is sent to AxesWeb for this feature.

Additionally, when you verify your API key from the plugin settings, the plugin makes a request to the AxesWeb verification API to validate your license.
What data is sent and when: 
– On verification: your site URL and the API key you enter are sent in a JSON request to the verification endpoint to confirm validity and activate features. 
– No periodic personal data transfers occur. A lightweight validity recheck may occur based on stored TTL to keep the activation status up to date.
