+# Field Color-Coding Based on Choice Values
+
+## Purpose
+Dynamically change the background color of any choice field on a form based on the selected backend value.
+
+## How to Use
+1. Create an OnChange client script on the desired choice field.
+2. Replace `'your_field_name'` in the script with your actual field name.
+3. Update the `colorMap` with relevant backend choice values and colors.
+4. Save and test on the form.
+
+## Key Points
+- Works with any choice field
+- Uses backend values of choices for mapping colors.
+
+## Demo
