Resolving Theme Color Overrides in IntelliJ Completion Popup #37

Title: Fixing IntelliJ Code Completion Popup color mismatch.

Description:
When using a custom theme in IntelliJ IDEA, the colors in the code completion popup may not match the theme's configuration due to IntelliJ overriding the theme settings with its default color scheme.

Steps to Fix:

1. Check IntelliJ's Color Scheme Settings

Even with the correct theme JSON, IntelliJ may override these settings with its default color scheme. To fix this:

1. Go to File > Settings > Editor > Color Scheme > General.
2. Look for the following settings under Popups and Hints > Completion:
   • Unselect the Background box.

3. Test the Changes

1. Restart IntelliJ IDEA to ensure all changes take effect.
2. Open the code completion popup and verify the colors match your theme.
