There was a bug in older version that saved the theme level color pallet on the page level when you saved page level settings. If you then change the colors in the theme level pallet, you would not see that change in any module because the page level overrules the theme level. There is no reset option, so you have to remove it in another way.
Option 1
- Export the page design
- Create a new page and import the design.
- Delete the old page (also from the recycle bin) and give the new page the same name and url.
Option 2
Remove it from the database with phpMyAdmin.
To select the record with the color pallet (replace wp_ with the prefix used in your database and 120 with the postid of the page from where you want it removed).
SELECT * FROM `wp_postmeta` where post_id="120" and meta_key="_et_pb_color_palette"

To delete the record
DELETE FROM `wp_postmeta` where post_id="120" and meta_key="_et_pb_color_palette"
